Matthew 16:26-28

For what shall a man be profited, if he shall gain the whole world, and forfeit his life? or what shall a man give in exchange for his life? For the Son of man shall come in the glory of his Father with his angels; and then shall he render unto every man according to his deeds. Verily I say unto you, There are some of them that stand here, who shall in no wise taste of death, till they see the Son of man coming in his kingdom.
