Romans 12:1-2
I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. 2 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.

What good is it to gain the whole world, yet forfeit your soul?

Your eternal destiny rests on the well-being of your soul.
