Galatians 4:1-7

Now I am saying, so long as the heir is underage, he is no different from a slave, even though he is the owner of everything. Instead, he is under guardians and managers until the date set by the father. So also, when we were underage, we were subservient to the basic principles of the world. But when the fullness of time came, God sent out His Son, born of a woman and born under law— to free those under law, so we might receive adoption as sons. Now because you are sons, God sent the Ruach of His Son into our hearts, who cries out, “Abba! Father!” So you are no longer a slave but a son—and if a son, also an heir through God.
