The Lord said, "And as you wish that men would do to you, do so to them. If you love those who love you, what credit is that to you? For even sinners love those who love them......
But love your enemies, and do good, and lend, expecting nothing in return; and your reward will be great, and you will sons of the Most High: for he is kind to the ungrateful and the selfish. Be merciful, even as your Father is merciful.
