Jesus condemns an unrighteous anger. This is when we get upset at an offence to ourselves, when we are treated in ways that we think are wrong, or when our pride is hurt or challenged. 1 This is the kind of anger that must be confronted, because it serves as the basis for most murder, 2 and should thus be seen as equivalent to the deed itself. 3 Cain and Abel showed that jealous anger is the root of murder. 4 The apostle John will also confirm that unrighteous anger is murder in the mind (1 John 3:15) and should not be seen among God’s people. 5 From this we see that God does not simply want an outward obedience but conformity from the heart (see Deuteronomy 5:29; Deuteronomy 30:6). 6 His people must be holy as he is holy (see Leviticus 19:2; Deuteronomy 18:13; Matthew 5:48). 7
22 But I say to you that everyone who is angry with his brotherwill be liable to judgment; whoever insultshis brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hellof fire.
