Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect (Rom. 12:2 ESV).
In today's society we are told just to go along with everyone else and we will be fine. But in the Bible we are told repeatedly that that we are "not of the world" (John 15:19), for Christ has called us to be with Him.
