Matthew 16:25-29

For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.

For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?

For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.

Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
