Galatians 4:8-11 CEB
At the time, when you didn’t know God, you were enslaved by things that aren’t gods by nature. But now, after knowing God (or rather, being known by God), how can you turn back again to the weak and worthless world system? Do you want to be slaves to it again? You observe religious days and months and seasons and years. I’m afraid for you! Perhaps my hard work for you has been for nothing.
