Mark 8:34-38

34 He called the multitude to himself with his disciples, and said to them, "Whoever wants to come after me, let him deny himself, and take up his cross, and follow me.

35 For whoever wants to save his life will lose it; and whoever will lose his life for my sake and the gospel's will save it.

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

37 For what should a man give in exchange for his life?

38 For whoever will be ashamed of me and of my words in this adulterous and sinful generation, the Son of Man also will be ashamed of him, when he comes in the glory of his Father with the holy angels."
