Here’s from the New Testament Bible, that I am no longer a “slave” but a daughter / son of God.
“Sons and Heirs
…5so that He might redeem those who were under the Law, that we might receive the adoption as sons. 6Because you are sons, God has sent forth the Spirit of His Son into our hearts, crying, “Abba! Father!” 7Therefore you are no longer a slave, but a son; and if a son, then an heir through God.” Gal. 4:6
