Luke 6:31-35

and as you wish that men may do to you, do also to them in like manner;

and—if you love those loving you, what grace is it to you? For also the sinful love those loving them;

and if you do good to those doing good to you, what grace is it to you? For also the sinful do the same;

and if you lend to those of whom you hope to receive back, what grace is it to you? For also the sinful lend to sinners—that they may receive again as much.

But love your enemies, and do good, and lend, hoping for nothing again, and your reward will be great, and you will be sons of the Highest, because He is kind to the ungracious and evil;
