Do Not Cheat.
John 15:18-27 18 “If the world hates you, (A) keep in mind that it hated me first. 19 If you belonged to the world, it would love you as its own.
"Do not make friends with a hot-tempered person, do not associate with one easily angered, or you may learn their ways and get yourself ensnared” (Proverbs 22:24-25).
Matthew 5:44 Jesus says, “But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you.”
Romans 12:19 "Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, "Vengeance is mine, I will repay, says the Lord." Do not take revenge, my dear friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay," says the Lord."
