Romans 12:2
Do no conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is; His good, pleasing and perfect will.

Christian, there is a battle going on for your mind.
satan is lying to us, trying to make us think we have the right to decide what is true, what is wrong and what is right. 

Renewing our mind helps us recognize the lies of the enemy, by comparing them to God’s Word.
