Continually act mercifully toward others, because God will not act mercifully to those who do not act mercifully toward others.

James 2:12-13

12 Continually speak and act toward others as people should who will be judged {whom God will judge} by the law that frees us from being punished {God punishing us} for our sins. 13 Speak and act like that, because when God judges us, he will not act mercifully toward those who do not act mercifully toward others. But when we are merciful to others, we can rejoice, because our being merciful shows that we are acting like people whom God has mercifully saved from being judged (OR, we can rejoice because God will judge us mercifully).
