Jesus speaks of the future and of the cost of discipleship

^31-33 And he began to teach them that it was inevitable that the Son of Man should go through much suffering and be utterly repudiated by the elders and chief priests and scribes, and be killed, and after three days rise again. He told them all this quite bluntly. This made Peter draw him on one side and take him to task about what he had said. But Jesus turned and faced his disciples and rebuked Peter. “Out of my way, Satan!” he said. “Peter, you are not looking at things from God’s point of view, but from man’s!”

^34-38 Then he called his disciples and the people around him, and said to them, “If anyone wants to follow in my footsteps, he must give up all right to himself, take up his cross and follow me. The man who tries to save his life will lose it; it is the man who loses his life for my sake and the Gospel’s who will save it. What good can it do a man to gain the whole world at the price of his own soul? What can a man offer to buy back his soul once he has lost it? If anyone is ashamed of me and my words in this unfaithful and sinful generation, the Son of Man will be ashamed of him when he comes in the Father’s glory with the holy angels around him.”
