Mark 8: 31-9:1
And he began to teach them that the Son of man must suffer many things, and be rejected by the elders and the chief priests and the scribes, and be killed, and after three days rise again. And he said this plainly. And Peter took him, and began to rebuke him. But turning and seeing his disciples, he rebuked Peter, and said, "Get behind me, Satan! For you are not on the side of God, but of men."
And he called to him the multitude with his disciples, and said to them, "If any man would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it; and whoever loses his life for my sake and the gospel's will save it. For what does it profit a man, to gain the whole world and forfeit his life? For what can a man give in return for his life? For whoever is ashamed of me and of my words in this adulterous and sinful generation, of him will the Son of man also be ashamed, when he comes in the glory of his Father with the holy angels."
And he said to them, "Truly, I say to you, there are some standing here who will not taste death before they see that the kingdom of God has come with power."
