Promise Before Law: Living as God's Children in Christ

Paul presses the Galatians to get the order right. God made a promise to Abraham long before the law arrived, and the law, coming four hundred and thirty years later, could not cancel what God had already signed, sealed, and established. The promise came first. The rules on the fridge do not rewrite the will.

God promised Abraham blessing, descendants, land, and finally one particular descendant, Jesus. Galatians 3 insists that inheritance comes by promise, not performance. If the inheritance depends on law keeping, then it is no longer gift. If God gives it by promise, then a person does not earn it by proving worth. Obedience still matters, but obedience cannot become a ladder up to God. Once obedience becomes a way to establish value, even good works get twisted into pride, comparison, and self-protection.

The law still has a good and holy purpose. Paul asks the obvious question, “Why then was the law given at all?” The law was given because of transgressions. It names sin. It brings sin into the open. Like a diagnosis from a doctor, the law tells the truth and ends denial, but it cannot heal the disease. The law cannot undo yesterday’s words, repair every wound, remove guilt, or give a new heart. If any law could impart life, righteousness would have come that way. But Jesus is the way, the truth, and the life.

Paul gives two pictures for the law. The law was like a prison guard, holding Israel in custody until Christ came. The law was also like a guardian, supervising a child until adulthood. That stage had a real purpose, but the promised offspring has now arrived. Christ has come, so going back under the Mosaic covenant as though Christ had not come is like a grown man sitting in a child’s classroom, or a fully licensed driver asking to go back on L plates.

Christ does what the law cannot do. Christ lives the obedient life sinners could not live, bears the curse they deserved, gives forgiveness, and pours out the Spirit. In Christ Jesus, believers are children of God through faith. Baptism into Christ means being clothed with Christ, not clothed in success, respectability, attractiveness, confidence, or religion.

Paul finishes by flattening every false spiritual ranking. Jew or Gentile, slave or free, male or female, none of those differences determine standing before God. If a person belongs to Christ, that person is Abraham’s seed and an heir according to the promise. Christianity does not start with do. It begins with done.

Key Takeaways

• 1. Promise comes before the rules God’s promise to Abraham was not a rough draft waiting for Moses to tidy it up. The law came later, and it could not cancel the covenant God had already established by grace. Obedience becomes Christian only when it flows from promise, not when it tries to purchase acceptance. [27:46]
• 2. The law diagnoses, not heals God’s law tells the truth about sin with painful accuracy. It reaches beneath visible behaviour and exposes desire, pride, resentment, and the deep resistance to being ruled by God. But the diagnosis cannot give life, which is why the exposed sinner must run to Christ rather than negotiate with the commandment. [34:01]
• 3. Christ fulfils the guardian’s work The law guarded, restrained, exposed, and preserved Israel until the promised one came. Once Christ arrived, returning to the old covenant as a basis for standing with God made no sense. The law remains a wonderful guide, but it is a terrible saviour. [37:54]
• 4. Christ clothes the empty-handed Human beings keep trying to dress themselves in success, reputation, morality, confidence, or religion. None of those identities can bear the weight placed on them. Faith receives a better clothing, Christ himself, so standing before God rests on him rather than a stained and inconsistent record. [42:25]
• 5. No first-class Christians exist Paul refuses every spiritual ranking system that makes one believer closer to God than another. Ancestry, status, sex, background, education, wealth, age, and church history do not alter access to Christ or share in the inheritance. Every child of God comes the same way, empty handed, through faith in Jesus.

Bible Reading

Galatians 3:15-29
“Brothers and sisters, let me take an example from everyday life. Just as no one can set aside or add to a human covenant that has been duly established, so it is in this case. The promises were spoken to Abraham and to his seed. Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ. What I mean is this: The law, introduced 430 years later, does not set aside the covenant previously established by God and thus do away with the promise. For if the inheritance depends on the law, then it no longer depends on the promise; but God in his grace gave it to Abraham through a promise. Why, then, was the law given at all? It was added because of transgressions until the Seed to whom the promise referred had come. The law was given through angels and entrusted to a mediator. A mediator, however, implies more than one party; but God is one. Is the law, therefore, opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, then righteousness would certainly have come by the law. But Scripture has locked up everything under the control of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe. Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed. So the law was our guardian until Christ came that we might be justified by faith. Now that this faith has come, we are no longer under a guardian. So in Christ Jesus you are all children of God through faith, for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.” [24:26]

Romans 7:7-12
“What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, "You shall not covet." But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead. Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. I found that the very commandment that was intended to bring life actually brought death. For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. So then, the law is holy, and the commandment is holy, righteous and good.” [30:34]

John 14:6
“Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me."” [35:05]

Observation questions

1. In Galatians 3, what timeline does Paul give between God’s promise to Abraham and the coming of the law, and what point is he making with that order? [27:46]
2. What reasons does Paul give for why the law was given, and what are the two pictures he uses to describe its role? [35:50]
3. In Romans 7, what example does Paul use to show how the law exposes sin beneath outward behaviour?
4. In Galatians 3:26-29, what words or phrases describe the believer’s new status in Christ?

Interpretation questions

1. If the inheritance comes by promise and not by law, what does that say about the way a person receives acceptance from God? How does that challenge the instinct to measure spiritual standing by performance? [23:18]
2. Paul says the law was given because of transgressions, and Romans 7 shows that it exposes sinful desire. Why is that exposing work necessary, even though the law cannot heal or give life? [34:01]
3. Paul says the law was a guardian until Christ came. What would it look like, in a practical church or personal sense, to go back under the guardian as though Christ had not yet come? [39:05]
4. Paul says believers are clothed with Christ and are all one in him. How does that reshape the way Christians should think about status, background, respectability, and belonging? [43:26]

Application questions

1. Where is the strongest temptation right now to prove worth through obedience, morality, usefulness, or religious effort? What happens to the heart when obedience becomes a way to earn acceptance instead of a response to grace? [28:32]
2. The law diagnoses but does not heal. When sin is exposed, is the first instinct to hide, defend, compare, or run to Christ? What would it look like this week to bring sin into the open before God more honestly? [34:01]
3. Many people try to clothe themselves with success, respectability, confidence, attractiveness, or being seen as a “good Christian.” Which of those coverings is most tempting, and how has it failed to carry the weight of identity? [42:25]
4. In Christ there are no first-class Christians. Where does the temptation still show up to rank people by background, maturity, education, culture, age, or church history? How might that be shaping relationships in subtle ways? [44:39]
5. “Christianity doesn’t start with do; it begins with done.” Where in daily life is that hardest to remember: parenting, work, church, marriage, singleness, suffering, or private guilt? Why there? [49:38]
6. Since believers are children of God through faith, how might that change the way failure is handled this week? What would it look like to admit failure without being crushed by it? [29:11]
7. Grace comes before obedience. If that order really settled more deeply into the heart, what might change in the way children, friends, or newer believers are spoken to about sin and growth? [47:34]
