To gain the whole world is not worth the price of one's soul

Scripture references

Matthew 16:24–27 (ASV)

24Then said Jesus unto his disciples, If any man would come after me, let him deny himself, and take up his cross, and follow me. 25For whosoever would save his life shall lose it: and whosoever shall lose his life for my sake shall find it. 26For 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? 27For 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.

Luke 9:23–27 (ASV)

23And he said unto all, If any man would come after me, let him deny himself, and take up his cross daily, and follow me. 24For whosoever would save his life shall lose it; but whosoever shall lose his life for my sake, the same shall save it. 25For what is a man profited, if he gain the whole world, and lose or forfeit his own self? 26For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he cometh in his own glory, and the glory of the Father, and of the holy angels. 27

When a backslidden C.T. Studd was restored back to fellowship with God, in answer to the prayer of two old ladies, he found a love of which he could not let go. No longer could things of this world satisfy him; he found Jesus sweeter than all else. To do His will and to live for things that will last, became his primary preoccupation!
