Mark 8:34-38

34 And calling the multitude together with his disciples, he said to them: If any man will follow me, let him deny himself and take up his cross and follow me.

35 For whosoever will save his life shall lose it: and whosoever shall lose his life for my sake and the gospel shall save it.

36 For what shall it profit a man, if he gain the whole world and suffer the loss of his soul?

37 Or what shall a man give in exchange for his soul:

38 For he that shall 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 shall come in the glory of his Father with the holy angels.
