Anger and Murder!?

I know that many people have killed others because of their "anger attacks, but  it is so interesting how in the Bible 'Just' being angry IS like murdering! As I was reading Matthew 5: 21-25 it surprised me how if you have problems with anyone around you it is subject to judgement. This chapter even says that if we are living having unresolved matters with our brother we are in danger of the fire of hell! That is pretty serious! It even goes on to serving at church (i saw it this way), if we are serving at church and are not completely clear of issues, Jesus commands us to leave our "gifts" in front of the altar to reconcile with our brother and to THEN after that to go and offer our gifts. Jesus tells us to resolve any problems immediately because if not, we are going to be put into prison and not get out until we have paid every last bit. This makes me think about times when forgiving someone or asking for forgiveness has been so hard. I want to make sure to have all matters resolved and in peace with everyone.
