Galatians 4:1-5 KJV
[1] 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.
Let that sink in.
