Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.
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?
- Book of Matthew 16:24-26

For this is the love of God, that we keep his commandments: and his commandments are not grievous.
For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. - 1 John 5:3-4
