Mark 8:31-38

And he began to teach them that the Son of man must suffer many things, and be rejected of the elders and of the chief priests and of the scribes, and be killed, and after three days rise again. And he spoke the thing openly. And Peter, taking him to him, began to rebuke him. But he, turning round and seeing his disciples, rebuked Peter, saying, Get away behind me, Satan, for thy mind is not on the things that are of God, but on the things that are of men. And having called the crowd with his disciples, he said to them, Whoever desires to come after me, let him deny himself, and take up his cross and follow me. For whosoever shall desire to save his life shall lose it, but whosoever shall lose his life for my sake and the gospel's shall save it. For what shall it profit a man if he gain the whole world and suffer the loss of his soul? for what should a man give in exchange for his soul? For whosoever shall be ashamed of me and of my words in this adulterous and sinful generation, of him shall the Son of man also be ashamed when he shall come in the glory of his Father with the holy angels.
