Galatians 4:4-9

But when the right time came, God sent his Son who was born of a woman and lived under the law. God did this so he could buy freedom for those who were under the law and so we could become his children. Since you are God’s children, God sent the Spirit of his Son into your hearts, and the Spirit cries out, “Father.” So now you are not a slave; you are God’s child, and God will give you the blessing he promised, because you are his child. In the past you did not know God. You were slaves to gods that were not real. But now you know the true God. Really, it is God who knows you. So why do you turn back to those weak and useless rules you followed before? Do you want to be slaves to those things again?
