Matthew 18:6,10
6 “But whoever causes one of these little ones who believe in Me to sin, it would be better for him if a millstone were hung around his neck, and he were drowned in the depth of the sea.
10 “Take heed that you do not despise one of these little ones, for I say to you that in heaven their angels always see the face of My Father who is in heaven.
Romans 12:17-21
Repay no one evil for evil. Have regard for good things in the sight of all men. If it is possible, as much as depends on you, live peaceably with all men. Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, “Vengeance is Mine, I will repay,” says the Lord. Therefore
“If your enemy is hungry, feed him;
If he is thirsty, give him a drink;
For in so doing you will heap coals of fire on his head.”
Do not be overcome by evil, but overcome evil with good.
