Galatians 5:15-17

15If you bite and devour each other, watch out or you will be destroyed by each other. 16So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 17For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever Or you do not do what you want.
