If everyone took care of others, all would be taken care of. When we seek to serve ourselves we are never truly satisfied.
For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. Matthew 16:25
27 And whosoever will be chief among you, let him be your servant: 28 Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many. Matthew 20:27-28
