Mark 8:30-37

30And he strictly charged them to tell no one about him.

31And 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.

32And he said this plainly. And Peter took him aside and began to rebuke him.

33But turning and seeing his disciples, he rebuked Peter and said, "Get behind me, Satan! For you are not setting your mind on the things of God, but on the things of man."

34And calling the crowd to him with his disciples, he said to them, "If anyone would come after me, let him deny himself and take up his cross and follow me.

35For whoever would save his life will lose it, but whoever loses his life for my sake and the gospel's will save it.

36For what does it profit a man to gain the whole world and forfeit his soul?

37For what can a man give in return for his soul?
