Love your enemies; pray for those who persecute you; do good to those
who hate you. If your enemy is hungry, feed him; if he is thirsty, give him
something to drink. Do not be conquered by evil, but conquer evil with good
(Rom. 12:17-21). Do not return evil for evil, or insult for insult. Return a
blessing instead.

Get rid of all bitterness, all passion and anger, harsh words, slander
and malice of every kind. In place of these, be kind to one another,
compassionate, and mutually forgiving, just as God has forgiven you. Do
nothing to sadden the Holy Spirit with whom you will be sealed for your day
of redemption (Eph. 4:29-32).
