Where can we go that God does not go?
As a Christian, we literally house His Spirit, permanently.
The legalist will say if we sin, He leaves, but that isn’t true.
Sure, before the Cross, God came and went based on righteous behavior and sins being atoned for by animal blood. But now, our sins have been taken away past, present and future by Jesus’ Blood. Yes, even future sins.
All of our sins were in the future when Christ died for them. He’ll never die again, which would be necessary to forgive you again. It is finished.
