The carnal self cannot live in harmony with the spiritual self. 

Numbers 33:52, 55 

Then drive out all the people living in the land in front of you. Destroy all their cut stones, and all their man-made gods, and all their high places. Drive out the people who live in the land in front of you. If you do not, then those who are allowed to stay will be like sharp pieces in your eyes and like thorns in your sides. They will trouble you in the land where you live.
