Matthew 5:25-26
Jesus Teaches on Anger
25 "Settle matters quickly with your adversary who is taking you to court. Do it while you are still with him on the way, or he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison. 26 I tell you the truth, you will not get out until you have paid the last penny.
Jesus teaches us about anger...He tells us we should not keep anger for long periods, but we should get over being angry quickly with our adversaries, and those we are angry with...
So settle anger issues quickly, as you possible can, and move on...Otherwise the consequences can and may get worse and grow...
Forgiving is one of the key teachings of Jesus and when one is angry and stays angry it is hard and maybe much harder to forgive...
