And he began to teach them that it was necessary for the Son of Man to suffer many things and to be rejected by the elders and the chief priests and the scribes, and to be killed, and after three days to rise. And he was speaking openly about the subject, and Peter took him aside and began to rebuke him. But turning around and seeing his disciples, he rebuked Peter and said, “Get behind me, Satan, because you are not setting your mind on the things of God, but the things of people!” And summoning the crowd together with his disciples, he said to them, “If anyone wants to come after me, let him deny himself and take up his cross and follow me. For whoever wants to save his life will lose it, but whoever loses his life on account of me and of the gospel will save it. For what does it benefit a person to gain the whole world and forfeit his life? For what can a person give in exchange for his life? For whoever is ashamed of me and my words in this adulterous and sinful generation, the Son of Man will also be ashamed of him when he comes in the glory of his Father with the holy angels.”
