Ephesians 2:8–9
"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast."
The clearest gospel summary in Scripture. Paul stacks three denials — not of yourselves, not a work, not ground for boasting — to shut every human contribution to salvation. Grace is not a reward; it is a gift. Faith is the hand that receives it, not the price that earns it.
2 Corinthians 12:9
"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."
God's answer to Paul's desperate prayer was not removal of the thorn but an assurance of sufficiency. Grace here is not positional but experiential — active power meeting active need. The weaker you are, the more visibly grace works.
Romans 3:23–24
"For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus."
Paul levels the entire human race in one verse and then lifts them all in the next. "Freely" translates the Greek dorean — as a free gift, without cost. Justification is the legal declaration; grace is the ground it stands on; redemption through Christ is the means.
Titus 2:11
"For the grace of God that bringeth salvation hath appeared to all men."
Paul describes grace as appearing — as though it is a person who stepped onto the stage of history. The incarnation of Christ is the appearing of grace. This grace is not tribal or selective; it has appeared to all men, making the gospel genuinely universal in its reach.
John 1:16
"And of his fulness have all we received, and grace for grace."
The phrase "grace for grace" (or "grace upon grace") suggests an inexhaustible supply — wave after wave, measure after measure. Believers do not receive grace once at conversion; they receive from an infinite reservoir that never depletes. The fullness of Christ is the source.
Romans 5:20
"Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound."
Paul uses a Greek comparative that means grace did not merely match the increase of sin — it superabounded. No depth of sin exhausts the supply of grace. This verse is not a license to sin (Paul addresses that directly in chapter 6) but a declaration that God's grace is always greater.
