Galatians 4 explained: From Servants to God's Children

An heir not yet grown (vv. 1-3)

In Paul's world, a child who would inherit everything still lived under guardians until the age his father set, with no more say than a servant. Paul says people before Christ were like that, held under the basic forces or principles of the world, a phrase scholars still debate: it may mean beginner religious rules, spiritual powers, or both.

Adopted into the family (vv. 4-7)

At the time God chose, his Son was born as a human and as a Jew living under the law of Moses, to free those under it and make them full children by adoption. God's Spirit lets them call God 'Abba,' the Aramaic word a child used for father, so they are now heirs, not servants.

Why go back? (vv. 8-11)

The Galatians were non-Jews who once served gods Paul says are not real gods. Now they were being told to keep Jewish festivals and calendar rules in order to belong, and Paul sees this as trading one kind of bondage for another.

A personal appeal (vv. 12-20)

Paul reminds them that he first came to them while ill, and they welcomed him like an angel, so devoted they would have given him their own eyes. Now rival teachers are courting them to pull them away from him, and he feels like a mother in labor again until Christ takes shape in them.

Two mothers, two agreements (vv. 21-27)

Abraham had Ishmael by Hagar, an enslaved woman, and Isaac by Sarah, born after God's promise, and Paul reads them as a figure: Hagar stands for the agreement made at Mount Sinai and the Jerusalem of his day, Sarah for a free Jerusalem in heaven. He backs this with Isaiah's song to a childless woman, picturing the family of the promise growing large.

Children of the promise (vv. 28-31)

Paul tells the non-Jewish believers they are like Isaac, and compares the pressure they face to the old story of Ishmael mistreating Isaac. He uses Sarah's harsh demand from Genesis 21 to say the rival teaching must be sent away, which many scholars read as aimed at those teachers, not at Jewish people in general.

Key verse: Galatians 4:7

Where Christians differ

Christians differ on whether Paul is rejecting the law of Moses as a way of earning a right standing with God, or more specifically rejecting the demand that non-Jews adopt Jewish customs like circumcision and the calendar to belong to God's people.

Something to think about

Why might an old set of rules or expectations feel safer than freedom, even to someone who believes they have outgrown it?
