Mark 10:21

21. Then Jesus beholding him loved him, and said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me.

Mark 8:34-37

34. And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me.
35. For whosoever shall 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?

Proverbs 16:32

32. He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.
