Galatians 4:1-5

Let me illustrate: As long as an heir is a minor, he’s not really much different than a servant, although he’s the master over all of them. For until the time appointed by the father, the child is under the domestic supervision of the guardians of the estate. So it is with us. When we were juveniles we were enslaved under the hostile spirits of the world. But when the time of fulfillment had come, God sent his Son, born of a woman, born under the law. Yet all of this was so that he would redeem and set free those held hostage to the law so that we would receive our freedom and a full legal adoption as his children.
