Mark 8:35-38

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? If you are ashamed of me and my words while living among sinful and faithless people, then I, the Son of Man, will also be ashamed of you when I make my appearance with my holy messengers in the glorious splendor of my Father!”
