“You have heard that it was said to those of old, ‘You shall not murder; and whoever murders will be liable to judgment.’ But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hell of fire. So if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift.” – Matthew 5:21-24 (ESV)
Anger poisons our spirits.
Comparing a heart filled with anger to the act of murder, in this teaching Jesus makes a decisive and powerful statement about how seriously God looks at wrathful intent. For us to truly commune with our Heavenly Father as He desires of us, we need to lay our resentment, hate and anger at the foot of the Cross and petition God’s attention with a joyful and open heart.
