Galatians 4:8; Galatians 4:9; Galatians 4:25; Galatians 5:13

8 However at that time, when you did not know God, you were slaves to those which by nature are no gods.

9 But now that you have come to know God, or rather to be known by God, how is it that you turn back again to the weak and worthless elemental things, to which you desire to be enslaved all over again?

25 Now this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.

13 For you were called to freedom, brethren; only do not turn your freedom into an opportunity for the flesh, but through love serve one another.
