Understanding Galatians 4:5-7: Adopted as God's Children

The Big Problem in Galatia: Freedom vs. Rules

To really grasp the power of Paul’s words in Galatians 4:5-7, it helps to understand the situation he was addressing.

Paul wrote this letter to churches in Galatia made up of both Jewish and Gentile believers, where some teachers were insisting that Gentiles must follow Jewish laws like circumcision to be true followers of Christ. This created a crisis: were people saved by trusting Jesus alone, or by Jesus plus keeping the law? Paul’s entire letter fights for the freedom found in Christ alone, warning that adding rules as a requirement for salvation distorts the gospel.

So when Paul says God sent His Son to redeem those under the law and grant us adoption as sons, he’s showing that Christ’s work frees us from trying to earn God’s favor - whether we were born under the law or not. The Spirit doesn’t come because we obey rules, but because we are now children through grace, able to cry out 'Abba! Father!' with confidence. This changes everything: we’re not slaves struggling to measure up, but sons who belong, and as sons, we’re heirs to all that God has promised.

Adoption, Abba, and the Spirit’s Witness

At the heart of Galatians 4:5‑7 is the truth that God forgives us and brings us into His family as adopted sons.

The word 'redeem' means to buy back or set free, like freeing a slave by paying a price. Jesus paid that price so we could be released from the law’s demands and its power to condemn us. But redemption isn’t the end - it leads to adoption, a legal act where God makes us His full-status children, not servants or outsiders. This is more than a status change. It is a family identity, and Paul emphasizes 'sons' to show we receive the full inheritance and authority of a first-century heir, even though many of us were once spiritually powerless. The Spirit’s cry of 'Abba! Father!' confirms this relationship - 'Abba' is the intimate, tender word for 'Daddy' or 'Papa,' the same word Jesus used in Mark 14:36 when He prayed to His Father in Gethsemane, showing we now share His closeness with God.

The Spirit helps us obey and testifies from within that we belong to God as His children, as Paul says in Romans 8:15‑17: 'For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba!”' Father!” The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs - heirs of God and fellow heirs with Christ.' This inner witness is not based on our performance but on our position in Christ. We’re no longer under fear or obligation, but in a relationship of love and confidence.

The Spirit doesn’t just help us obey; He testifies from within that we belong to God as His children.

So sonship means we’re no longer slaves to rules, guilt, or shame, but heirs who can trust God’s promises and live with boldness. This truth reshapes how we pray, face trials, and see ourselves - because if we are God’s children, nothing can remove our place in His family.

From Duty to Dad: Living in God’s Family

This shift from rule-keeping to relationship is at the heart of what it means to live as God’s children, not slaves.

The word 'Abba' reveals the startling intimacy God offers us - He’s not a distant ruler demanding perfection, but a loving Father we can approach like a child runs to their dad. In Paul’s day, this was radical: religion was about duty and fear, but now the Spirit lets us call the Almighty 'Papa,' showing we’re accepted not because of what we’ve done, but because of who we are in Christ.

So we’re no longer stuck trying to earn our way in. We’re sons and daughters who already belong, just as Jesus promised when He said, 'I will not leave you as orphans; I will come to you' (John 14:18).

Adoption Across the Story: From Israel to Jesus to Us

This truth of adoption isn’t unique to Galatians - it’s a central thread woven throughout Paul’s letters and the entire story of Scripture.

In Romans 8:14-17, Paul says, 'For all who are led by the Spirit of God are sons of God. For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs - heirs of God and fellow heirs with Christ.' This echoes Galatians, showing that the Spirit’s leading and our cry to God as Father are marks of true belonging. Likewise, Ephesians 1:5 declares that God 'predestined us for adoption as sons through Jesus Christ,' revealing that our sonship wasn’t an afterthought but part of God’s eternal plan.

And this adoption only became possible because Jesus Himself was the perfect Son. At His baptism, God said, 'You are my beloved Son; with you I am well pleased' (Luke 3:22), marking Jesus as the one who fulfilled all righteousness and opened the way for us to be called sons too. Where Israel in the Old Testament was called God’s son corporately but failed to live as one, Jesus as the true Son succeeded, and now we are brought into that sonship by grace. This means our identity isn’t based on performance but on union with Christ - just as He is loved, so are we. The old shadows of distant, fearful religion have given way to the reality of intimate relationship through the Spirit.

We don’t approach God with anxiety, trying to earn favor, but with confidence, like a child running to a good dad.

So in everyday life, this changes everything: we don’t approach God with anxiety, trying to earn favor, but with confidence, like a child running to a good dad. In church, this means we treat one another not as competitors in holiness but as brothers and sisters in the same family, showing grace, speaking truth in love, and lifting each other up. And in our communities, a church that lives like it’s truly adopted will be marked by bold hope, deep compassion, and fearless generosity - because we know we’re secure in the Father’s love, no matter what.
