What does Paul mean by comparing God’s promise to a human covenant?

Paul points to how people treat serious agreements. When a contract between people is confirmed, no one is allowed to cancel it or change it at will. He uses this simple picture to say that God’s promise to Abraham is at least that firm. If we respect human contracts, how much more should we trust God’s word. This helps show that the later giving of the law cannot undo or replace the earlier promise God freely gave to Abraham and his seed.

Who is the “seed” of Abraham in this passage, and why does it matter?

Paul notices that God spoke of Abraham’s “seed” in the singular, not “seeds.” He explains that this “seed” is Christ. This matters because it shows the promise is focused on Jesus and all who are joined to him, not on physical descent alone. The blessing and inheritance come through belonging to Christ, the promised offspring, rather than through keeping the law or simply being born into Abraham’s family line.

Why was the law added “because of transgressions”?

Paul says the law was added because of transgressions, meaning it was given to expose sin, show it clearly, and restrain it. The law makes people see how often they cross God’s commands, so they cannot pretend to be righteous on their own. It does not give life or make people right with God, but it prepares the way by showing the need for mercy. In this way, the law points people toward Christ, the one who fulfills the promise.

Is the law against the promises of God in this passage?

Paul strongly denies that the law is against God’s promises. The law and the promise have different roles. If a law could have given life and made people righteous, then righteousness would be by the law, and the promise would be emptied. But the law cannot do that. Instead, scripture declares everyone under sin so that the promised blessing comes through faith in Jesus to those who believe. The law does not fight the promise; it prepares for it.

What does it mean that the scripture has “concluded all under sin”?

When Paul says scripture has concluded all under sin, he means God’s written word shows that every person, without exception, is a sinner. No one can claim to be right with God by their own efforts. This levels the ground for all people, both Jews and Gentiles. The result is that the only way to receive what God promised is by faith in Jesus. The promise is given, not earned, and it comes to those who trust in Christ rather than in their own works.

How was the law a “schoolmaster to bring us unto Christ”?

Paul pictures the law as a schoolmaster or guardian. In that time, such a person watched over children, kept them in line, and led them where they needed to go. In a similar way, the law watched over God’s people, taught them right and wrong, and showed their sin. This constant correction was meant to drive them to Christ, not to make them think they could earn righteousness. Once faith in Christ has come, believers are no longer under that guardian in the same way.

What changed “after faith came” according to this passage?

Paul says that before faith came, people were kept under the law and shut up unto the faith that would later be revealed. After faith came, meaning after Christ and his good news were clearly revealed and believed, believers are no longer under the law as a schoolmaster. Righteousness and belonging to God’s family no longer rest on living under that system, but on trusting Jesus. The believer’s standing with God now rests on faith, not on the law’s demands.

How does this passage explain the relationship between law and promise?

This passage teaches that God’s promise to Abraham came first and is unchangeable. The inheritance is given by promise, not earned by law. The law, given much later, did not replace or cancel the promise. Instead, the law exposed sin, restrained it, and acted like a guardian until Christ, the promised seed, came. Law and promise have different purposes: the promise gives the blessing by grace through faith, while the law shows our need for that grace.

Gal.3.15

Galatians 3:15

KJV

Brethren, I speak after the manner of men; Though it be but a man’s covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.

The Purpose of the Law

Brethren, I speak after the manner of men; Though it be but a man’s covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.

Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.

And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.

For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise.

Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.

Now a mediator is not a mediator of one, but God is one.

Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.

But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.

But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.

Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.

But after that faith is come, we are no longer under a schoolmaster.
