Galatians 4:7-9

Amplified Bible

⁷ Therefore you are no longer a slave (bond-servant), but a son; and if a son, then also an heir through [the gracious act of] God [through Christ].

⁸ But at that time, when you did not know [the true] God and were unacquainted with Him, you [Gentiles] were slaves to those [pagan] things which by [their very] nature were not and could not be gods at all. ⁹ Now, however, since you have come to know [the true] God [through personal experience], or rather to be known by God, how is it that you are turning back again to the weak and worthless elemental principles [of religions and philosophies], to which you want to be enslaved all over again?
