“Whoever is angry with his brother will be liable to judgment.” Jesus is looking to what may be behind “thou shalt not kill.” What motivates us to do such a terrible thing often starts out with pent-up anger. Anger is an emotion and as such is “neutral.” It is what the anger leads to that becomes sinful. Repressed anger is called depression. We have to have some outlet for our anger so it doesn’t hurt anyone. And, if we are really angry with someone, then let us be reconciled. We live out our love for God in our relationships with one another.
