Mark 8:37

For whoever wants to save his life will lose it; and whoever will lose his life for my sake and the sake of the Good News will save it.

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

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.
