Galatians 4:6-9

Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “ Abba, Father.” So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir. Formerly, when you did not know God, you were slaves to those who by nature are not gods. But now that you know God—or rather are known by God—how is it that you are turning back to those weak and miserable forces? Do you wish to be enslaved by them all over again?
