Galatians 4:6-9

And because we are his children, God has sent the Spirit of his Son into our hearts, prompting us to call out, “Abba, Father.” Now you are no longer a slave but God’s own child. And since you are his child, God has made you his heir. Before you Gentiles knew God, you were slaves to so-called gods that do not even exist. So now that you know God (or should I say, now that God knows you), why do you want to go back again and become slaves once more to the weak and useless spiritual principles of this world?
