The Abrahamic Covenant: Proof God's Promise Still Stands

From the sermon preached on July 12, 2026

If a promise made between two ordinary people cannot be broken once it is signed and settled, how much more can you trust the Abrahamic covenant God made long before any law existed? That question sits at the center of Galatians 3:15-29, where the apostle Paul argues that God's promise to Abraham was never conditional on human performance. It was a gift, sealed centuries before Moses ever received the law, and it still stands today for anyone who trusts in Jesus Christ.

Pastor Greg Freyer walked through this passage this week, building on the previous week's look at Galatians 3:1-14, where Paul used Abraham to show that people are justified by faith rather than by keeping the law. This week's message pushes further into the Abrahamic covenant itself: what it promised, why the law came 430 years later without canceling it, and what it means for someone who has never felt "good enough" to be part of God's family.

Paul opens with an everyday illustration. Once two people sign and settle a covenant, no one can go back and quietly add to it or take something away.

If that is true of an ordinary human agreement, Paul argues, it is far more true of the promise God made to Abraham. God keeps his promises, and this one was never up for renegotiation.

That promise, found in Galatians 3:16, pointed beyond Abraham's physical descendants to one specific "seed", Jesus Christ. Hebrews 6:18-19 backs this up, describing the hope believers have as an anchor for the soul, steady and unmoved no matter what happens around it. God keeps his promises because his own character will not allow him to lie.

Paul's point in verse 17 lands hard: the law showed up 430 years after the promise, and it could not cancel what had already been settled. For anyone who has ever wondered whether God's word can actually be trusted when life feels unstable, this is the honest answer Paul gives, not a slogan, but a legal argument rooted in how promises actually work.

One small, honest step today: name one promise from Scripture you have doubted lately, and simply reread it slowly before you decide it is not for you.

If the promise came first and settled everything, a fair question follows: why was the law ever given? Paul answers this directly in Galatians 3:19, saying the law "was added because of transgressions." The purpose of the law was never to save anyone; it was to reveal sin so people could recognize their need for a savior.

Romans 7:7-8 makes the same point from a different angle. Paul admits he would not have known his own sin without the law naming it.

The purpose of the law, in other words, is diagnostic. It shows you the problem; it was never designed to be the cure.

Paul goes further in verse 23, describing the law as something that "kept" people, a word that carries the sense of being guarded by a military escort. There was no slipping out from under it.

Romans 3:20-22 confirms that no one is justified "by the deeds of the law," because righteousness comes only through faith in Jesus Christ. Once you understand the purpose of the law this way, guilt loses its grip; it was only ever meant to point somewhere else.
A small, honest step today: instead of measuring yourself against a rulebook, ask what the rule was actually trying to show you about your need for help.

This is where the sermon turns from explanation to invitation. Galatians 3:26-29 says plainly, "For ye are all the children of God by faith in Christ Jesus." Once someone trusts Christ, Paul says, they are "baptized into Christ" and have "put on Christ", adopted into God's family regardless of background, status, or ethnicity.

Pastor Greg illustrated this with a picture from home: walking onto a Navy base in New Zealand, anyone can spot who belongs by what they are wearing. But wearing the uniform does not make someone a sailor; belonging does.

In the same way, being a child of God by faith is not about performing well enough to earn a uniform. It is about genuine belonging through Christ.

Ephesians 2 describes what life looked like before this adoption, following the flesh and its desires with no real direction. Being a child of God by faith changes that completely. Acts 13:39 adds one final confirmation: everyone who believes is justified from everything the law of Moses never could fix, red, yellow, black, white, or anywhere in between.

A small, honest step today: if you have carried the weight of not being "good enough," consider that adoption was never based on your performance to begin with.

Galatians 3 draws a clear line between two ways of relating to God, and Paul's argument throughout the chapter, including the promise summarized in Galatians 3:26, comes down to a simple contrast.

This table reflects exactly what Paul unpacks across Galatians 3:15-29: the law had a real, necessary job, but it was never the same job as the promise. Both matter, but only one saves.

Wondering whether any of this could actually change a Monday morning, not just a Sunday feeling, is a fair question. That kind of change usually happens slower than a sermon and more through people who show up consistently, whether you are in Mangapapa, Kaiti, or anywhere else across the wider Tairāwhiti region.

Bay Light Baptist Church meets each week at Mangapapa School Hall, and the invitation is simple: come as you are, with no pressure to have it figured out first. Whether your week has been steady or genuinely hard, there is a place to sit down and ask honest questions without anyone expecting a performance in return.

Paul's message across Galatians 3:15-29 is that the Abrahamic covenant was never canceled by the law, and it still holds for anyone who trusts Jesus Christ today. The law revealed the problem; the promise, kept perfectly by God, provides the answer through adoption into his family. That is not a technicality; it is the reason guilt does not have to be the last word.
