Mark 8:31-37

From then on, Jesus began to tell his disciples that he, the Son of Man, was destined to go to Jerusalem and suffer great injustice from the elders, leading priests, and religious scholars. He also explained that he would be killed and three days later be raised to life again. Jesus opened his heart and spoke freely with his disciples, explaining all these things to them. Then Peter took him aside and rebuked him. But Jesus turned around, and glancing at all of the other disciples, he rebuked Peter, saying, “Get out of my sight, Satan! For your heart is not set on God’s plan but man’s!” Jesus had his disciples and the crowd gather around him. And he said to them: “If you truly want to follow me, you should at once completely disown your own life. And you must be willing to share my cross and experience it as your own, as you continually surrender to my ways. 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?
