Mark 10:45

 For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.”

Joshua 24:15

But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.”

2 Corinthians 9:7

 Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.

John 15:13

Greater love has no one than this: to lay down one’s life for one’s friends.
