“You have heard that it was said to the people long ago, ‘You shall not murder, and anyone who murders will be subject to judgment.’ But I tell you that anyone who is angry with a brother or sister will be subject to judgment. Again, anyone who says to a brother or sister, ‘Raca,’ is answerable to the court. And anyone who says, ‘You fool!’ will be in danger of the fire of hell.
Matthew 5:21-22
You blind fools!
Matthew 23:17
Failing to deal with your anger will get in the way of faithfully following Jesus.
"The world becomes easier to understand and much less terrifying if you divide everything and everyone into friends and enemies, we and they, good and evil. The easiest way to unite a group isn't through love, because love is hard, It makes demands. Hate is simple."
- Fredrik Backman
Anger indicates that something is not ok.
"There is nothing that can be done with anger that cannot be done better without it."
- Dallas Willard
