Who was Paul?

Saul of Tarsus had credentials most religious leaders in the first century could only envy. A Pharisee of the Pharisees. Trained under Gamaliel, one of the most respected rabbis in Jerusalem. Zealous for the law in a way he would later describe as blameless by human standards. Deeply convinced that the sect following Jesus of Nazareth was a dangerous heresy that needed to be eradicated before it spread further.

That conviction made him dangerous. When Stephen became the first Christian martyr, stoned by an angry mob outside Jerusalem, Saul was there — not throwing stones himself, but holding the coats of the men who did. He approved of the killing (Acts 8:1). What followed was a full-scale persecution campaign: Saul going house to house, dragging men and women out of their homes, committing them to prison. Then he set his sights on Damascus, carrying letters from the high priest authorizing him to arrest and extradite any Christians he found there.

He never made it to Damascus as a persecutor. What he encountered on that road turned him into the most prolific apostle in the history of the church. He would go on to write thirteen New Testament letters — more than any other author. He planted churches across Asia Minor, Macedonia, Greece, and Rome. He was beaten with rods three times, whipped with thirty-nine lashes five times, shipwrecked three times, stoned and left for dead once, imprisoned repeatedly, and finally executed in Rome under Nero. He died for the faith he had once tried to destroy.

Paul's transformation was violent, disorienting, and lifelong

It is tempting to read Paul's conversion as a clean break — old life over, new life begun, everything resolved. His letters tell a more complicated story. The weight of his past did not simply disappear. He calls himself "the least of the apostles" because he persecuted the church of God (1 Corinthians 15:9). He calls himself "the chief of sinners" (1 Timothy 1:15) — not as performative humility, but as a man who remembered what he had done. The families of believers he imprisoned and killed did not forget. The suspicion with which the early church initially received him (Acts 9:26) was completely rational. Paul's transformation was real, but he carried his history with him into every city he entered.

"Saul, Saul, why persecutest thou me?"
Acts 9:4

That voice from the light did not speak Paul's new name. It used the old one — twice. The confrontation was personal, direct, and impossible to rationalize away. Paul had not been persecuting a religion. He had been persecuting a person. That realization, on the ground in the dust outside Damascus, is where his transformation actually began.

Beyond the guilt, Paul's life after conversion was layered with a different kind of suffering. Churches he poured himself into turned against him — the Galatians embraced false teachers almost immediately after his departure (Galatians 1:6), and the Corinthians questioned his apostleship, his appearance, and his authority (2 Corinthians 10:10). He wrote at least one letter from prison chains. He describes profound loneliness at the end of his life: "At my first answer no man stood with me, but all men forsook me" (2 Timothy 4:16). And underneath all of this ran the thorn — something God gave him specifically to prevent pride, something he prayed to have removed three separate times, and something God explicitly declined to take away.

"My grace is sufficient for thee: for my strength is made perfect in weakness."
2 Corinthians 12:9

That answer from God is one of the most significant in Scripture — not because it resolves Paul's pain, but because it reframes the entire purpose of the pain. The thorn was not a mistake. It was not a spiritual deficiency. It was a design. God refused to remove it because what the thorn was producing in Paul was worth more than what its removal would have brought.

Seven passages that define Paul's story

Acts 9:3–6

"And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven: And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me? And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks. And he trembling and astonished said, Lord, what wilt thou do? And the Lord directed him into the city."

The Damascus road is one of the most documented conversion experiences in history — Paul retells it himself in Acts 22 and Acts 26, in slightly different words each time, as the defining moment of his life. The phrase "it is hard for thee to kick against the pricks" suggests Paul had already been fighting an inner resistance to what he was doing. The blinding light did not start the work. It finished it.

Acts 9:17–19

"And Ananias went his way, and entered into the house; and putting his hands on him said, Brother Saul, the Lord, even Jesus, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy Ghost. And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized."

Notice that God sent a frightened ordinary disciple to restore the persecutor's sight. Ananias initially pushed back — "Lord, I have heard by many of this man, how much evil he hath done to thy saints" — and went anyway. The scales falling from Paul's eyes is both a physical event and the most vivid metaphor in the New Testament for what conversion actually is: seeing, for the first time, what was always there.

2 Corinthians 12:7–10

"And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. For this thing I besought the Lord thrice, that it might depart from me. And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me."

Paul prayed three times — the same number Jesus prayed in Gethsemane — and received the same answer: not removal, but a different kind of grace. The theological payload here is enormous. God's power is not displayed despite Paul's weakness. It is displayed through it. The thorn is the condition of the testimony, not an obstacle to it.

Philippians 3:7–8

"But what things were gain to me, those I counted loss for Christ. Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ."

This is Paul's personal profit-and-loss statement. His pre-conversion credentials — circumcision, tribal lineage, Pharisaic training, legal blamelessness — were the assets he built his identity on. He did not just set them aside. He reclassified them as liabilities. The Greek word translated "dung" is one of the strongest terms of contempt available. Paul is not being politely modest about his former life. He is declaring it worthless against what he found in Christ.

2 Corinthians 11:24–28

"Of the Jews five times received I forty stripes save one. Thrice was I beaten with rods, once was I stoned, thrice I suffered shipwreck, a night and a day I have been in the deep; In journeyings often, in perils of waters, in perils of robbers, in perils by mine own countrymen, in perils by the heathen, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren; In weariness and painfulness, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness. Beside those things that are without, that which cometh upon me daily, the care of all the churches."

This passage is Paul's resume — but it is the resume of a man defending his apostleship to a church that had begun to doubt him. His credentials are not victories. They are sufferings. The catalog is staggering: 195 lashes, three beatings with rods, a stoning, three shipwrecks, a night adrift at sea. He lists danger from every conceivable direction. Then he adds: "the care of all the churches" — as if the physical suffering were the easier part.

2 Timothy 4:6–8

"For I am now ready to be offered, and the time of my departure is at hand. I have fought a good fight, I have finished my course, I have kept the faith: Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing."

These are among Paul's last words — written from a Roman prison cell to Timothy while awaiting execution. He knows he is going to die. His tone is not anxious. It is final and certain. The three metaphors he uses — a sacrifice being poured out, a fight completed, a race finished — are all images of something costly that has run its full course. Paul does not die unfinished. He dies having said and done everything he was sent to say and do.

Galatians 2:20

"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."

This is Paul's most compressed statement of what conversion actually is. The old Saul — the one with the credentials, the zeal, the persecution warrants — is dead. The one still walking around is a different person animated by a different life. Notice the phrase "who loved me, and gave himself for me." After everything Paul knew about his own past, he believed this was personal. Not generic. For him. The persecutor was loved and included in the sacrifice anyway.

God did not remove the thorn. He said "My grace is sufficient."

If you expected God to reward Paul's faithfulness by taking away his suffering, Paul's biography will unsettle you. The thorn stayed. The beatings kept coming. The imprisonments continued. Churches still turned against him. At the end of his life, he was alone in a cell. God's answer to Paul's suffering was not resolution — it was presence, purpose, and a promise that the weakness was the point.

What God did for Paul, he did through Paul's circumstances rather than around them. He used Paul's former life as a persecutor as his most powerful credential — because no one could accuse a former chief persecutor of being naive about what he was giving up. He used Paul's suffering catalog as a platform, because suffering authenticated the message in a way comfortable prosperity never could. And he used Paul's thorn to keep him from pride, ensuring that every sermon, every letter, every church planting was carried out by a man who could not lose sight of his own dependence.

Acts 9:15–16

"But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel: For I will shew him how great things he must suffer for my name's sake."

2 Corinthians 4:7–10

"But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us. We are troubled on every side, yet not distressed; we are perplexed, but not in despair; Persecuted, but not forsaken; cast down, but not destroyed; Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body."

2 Corinthians 12:9–10

"And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong."

Philippians 4:11–13

"Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content. I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to suffer need. I can do all things through Christ which strengtheneth me."

2 Timothy 4:17

"Notwithstanding the Lord stood with me, and strengthened me; that by me the preaching might be fully known, and that all the Gentiles might hear: and I was delivered out of the mouth of the lion."

That last verse was written from prison, alone, with execution imminent. "The Lord stood with me." Not "the Lord removed me from the situation." Not "the Lord made it comfortable." The Lord stood with him inside it. That is the consistent shape of God's work in Paul's life — not a rescue from suffering, but a presence within it that made it possible to endure, and ultimately, to mean something.

Your worst chapter can become your testimony

Paul's story cuts through two of the most common forms of spiritual paralysis: the belief that your past disqualifies you, and the belief that your current limitation disqualifies you. On the first: Paul's past was not a liability God had to work around. It became his most powerful credential. The man who had destroyed families to stop the gospel was now the one explaining it to the world. His before-and-after was so extreme that no one could doubt the transformation was real. If your history makes you feel that you have traveled too far from God to be useful — Paul's story says otherwise.

On the second: if you carry something God won't remove — a thorn, a limitation, a chronic struggle that you have prayed about more than three times with no answer — Paul's experience offers a different frame. God did not remove Paul's thorn because Paul's weakness was precisely where God's power would be most visible. The weakness was not the obstacle to the work. The weakness was the condition of the work. That does not make chronic struggle comfortable. But it gives it a direction and a purpose that bare endurance never can.

Paul also writes "I have learned, in whatsoever state I am, therewith to be content" — using the word learned. Contentment under suffering is not a spiritual gift distributed at conversion. It is a skill acquired through the repeated experience of being in difficult conditions and finding that God was there. Paul learned contentment the way you learn anything: by practicing it badly at first, then better, across years of actual hardship. Your current practice ground is not wasted. It is the curriculum.

Reflection questions

  • Paul describes his past — including his role in persecuting Christians — as the thing that qualified him to testify about grace. Is there any part of your own history that you have dismissed as a disqualifier, that might actually be the most powerful part of your testimony? What would it look like to own it rather than hide it?
  • God told Paul explicitly why the thorn was staying: to prevent pride, and to display strength in weakness. If God has declined to remove something from your life despite repeated prayer, is there any possibility that its presence is producing something in you that its removal would have prevented? What might that be?
  • Paul writes in Philippians 4 that he "learned" contentment — it was not natural, it was acquired through practice across difficult circumstances. Where in your current season is God training you toward a contentment you do not yet have? What is the specific condition being used as the classroom?
  • At the end of his life, alone in prison, Paul writes "the Lord stood with me." Not "rescued me" — stood with me. What does the distinction between rescue and accompaniment mean to you in your present circumstances? Is there comfort in a God who stays present inside the difficulty rather than only resolving it?

Frequently asked questions

What was Paul's thorn in the flesh?

Scripture does not identify Paul's thorn in the flesh with precision, which is likely intentional — its ambiguity allows every suffering believer to find themselves in it. In 2 Corinthians 12:7, Paul calls it "a thorn in the flesh, the messenger of Satan to buffet me." Proposed interpretations across church history include a chronic physical ailment (eye disease, epilepsy, migraines), recurring opposition from enemies, or spiritual oppression. What Scripture makes clear is that Paul prayed three times for it to be removed and God refused — saying instead, "My grace is sufficient for thee: for my strength is made perfect in weakness" (2 Corinthians 12:9). Whatever the thorn was, God chose to leave it because its presence was producing something removal would have destroyed.

How did Paul change from persecutor to apostle?

Paul's conversion was not gradual — it was sudden, physical, and overwhelming. On the road to Damascus with letters authorizing the arrest of Christians, he was struck down by a light from heaven and heard the voice of the risen Jesus: "Saul, Saul, why persecutest thou me?" (Acts 9:4). He was blinded for three days, neither eating nor drinking, until a disciple named Ananias came at God's command, laid hands on him, and restored his sight — at which point scales fell from his eyes and he was baptized. The man who left Jerusalem to destroy the church arrived in Damascus and immediately began preaching Christ in the synagogues. His transformation was so sudden and so complete that the early church initially refused to believe it was real (Acts 9:26).

What does Paul teach about suffering?

Paul's theology of suffering is one of the most developed in all of Scripture, and it was forged in personal experience — beatings, imprisonments, shipwrecks, hunger, betrayal, and a chronic thorn God refused to remove. His central teaching is that weakness is not a problem God needs to fix: it is the condition under which God's power is most fully displayed. "When I am weak, then am I strong" (2 Corinthians 12:10). He writes from prison that he has "learned, in whatsoever state I am, therewith to be content" (Philippians 4:11) — using the word "learned," indicating contentment under suffering is an acquired skill, not a natural one. He also reframes suffering as participation in Christ's death (Philippians 3:10) and as temporary preparation for an eternal weight of glory (2 Corinthians 4:17). Paul does not glorify suffering for its own sake. He glorifies what God does through it.
