Whoever calls another “fool” is in danger of hell fire. Matt.5:22 Do not swear at all. Matt.5:34-37
Do not resist an evil person. If slapped on one cheek, turn the other cheek also. Isaiah 50:6, Matt.5:39-41 (This does not mean we are not to resist Satan as he challenges us spiritually!)

Walk in love as Christ loved us even to the point of death as a sacrifice to God. Eph.5:2 (Give your anger and desire for revenge to God, for He says,) “Vengeance is Mine, I will repay. The Lord will judge His people. It is a fearful thing to fall into the hands of the living God. Hebrews 10:30-31
