Galatians 4:1-5
4 Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all;
2 But is under tutors and governors until the time appointed of the father.
3 Even so we, when we were children, were in bondage under the elements of the world:
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5 To redeem them that were under the law, that we might receive the adoption of sons.
Galatians 3:24-25
24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25 But after that faith is come, we are no longer under a schoolmaster.
If you have not fully trusted in Christ, you are under the law.
Under Christ, you are no longer under a schoolmaster.
Galatians 3:26
26 For ye are all the children of God by faith in Christ Jesus
