Ask God to bless those who persecute you – yes, ask him to bless, not to curse. Be happy with those who are happy, weep with those who weep. Have the same concern for everyone. Do not be proud, but accept humble duties. Do not think of yourselves as wise.

If someone has done you wrong, do not repay him with a wrong. Try to do what everyone considers to be good. Do everything possible on your part to live in peace with everybody. Never take revenge, my friends, but instead let God’s anger do it. For the scripture says, "I will take revenge, I will pay back, says the Lord." Instead, as the scripture says: "If your enemy is hungry, feed him; if he is thirsty, give him a drink; for by doing this you will make him burn with shame." Do not let evil defeat you; instead, conquer evil with good.

Romans 12:17-21
