Galatians 3:15 (KJV)

What does Galatians 3:15 mean?

Galatians 3:15 uses a human example to show that even a regular agreement or contract, once it is made official, cannot be changed or canceled by anyone. Paul is making the point that if this is true for human covenants, it is even more true for God’s promises.

Paul is writing to the believers in Galatia, explaining how God’s promise to Abraham is unchangeable. He calls them “brethren” to show he is speaking as a fellow believer. By comparing God’s promise to a human contract, Paul is preparing to show that the law given later does not cancel or add to God’s original promise.

The Greek behind Galatians 3:15

• διαθήκη (diathēkē; G1242): This word is often translated as “covenant” or “agreement.” In the ancient world, a διαθήκη was a binding contract, and Paul uses this term to highlight the seriousness and permanence of God’s promise.
• κυρόω (kuroō; G2964): This word means “to confirm” or “to make valid.” Paul’s use of κυρόω emphasizes that once a covenant is officially established, it cannot be undone or altered.
• ἀκυρόω (akuroō; G114): This means “to annul” or “to invalidate.” Paul’s point is that no one can nullify a confirmed covenant, making his argument about the unchangeable nature of God’s promise even stronger.

Why Galatians 3:15 matters

• Galatians 3:15 helps clear up the misunderstanding that the law given to Moses could change or override God’s earlier promise to Abraham.
• The verse emphasizes the reliability and permanence of God’s word, using a common human practice to make the point clear and relatable.
• This sets up Paul’s argument in the following verses, where he explains how the promise to Abraham and his “seed” (meaning Christ) stands at the center of God’s plan, not the later law.
