Galatians 4:6

But when the fullness of the time came, God sent out his Son, born to a woman, born under the law,

that he might redeem those who were under the law, that we might receive the adoption of children.

So you are no longer a bondservant, but a son; and if a son, then an heir of God.

However at that time, not knowing God, you were in bondage to those who by nature are not gods.
