James 4:7-8

7 Be subject therefore to God. But resist the devil, and he will flee from you.  8 Draw near to God, and he will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded. 

Romans 12:1-2

1 Therefore I urge you, brothers, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service.  2 Don't be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.
