Luke 6:32-35

(32) For if ye love them which love you, what Grace (thank) have ye? for sinners also love those that love them.

(33) And if ye do good to them which do good to you, what Grace (thank) have ye? for sinners also do even the same.

(34) And if ye lend to them of whom ye hope to receive, what Grace (thank) have ye? for sinners also lend to sinners, to receive as much again.

(35) But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind (Gracious) unto the unthankful (Ungracious) and to the evil.

Luke 17:9-10

(9) Doth he give grace (thank) that servant because he did the things that were commanded him? I think not.

(10) So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
