Mark 8:35-38
[35]For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel's, the same shall save it.
[36]For what shall it profit a man, if he shall gain the whole world, and lose his own soul?
[37]Or what shall a man give in exchange for his soul?
[38]Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.
