Mark 8:35-37

For if you let your life go for my sake and for the sake of the gospel, you will continually experience true life. But if you choose to keep your life for yourself, you will forfeit what you try to keep. For what use is it to gain all the wealth and power of this world, with everything it could offer you, at the cost of your own life? And what could be more valuable to you than your own soul?
