Be Angry, But Sin Not

Ephesians 4:26
“BE ANGRY, AND YET DO NOT SIN; do not let the sun go down on your anger.”

Anger is an uncomfortable emotion. It's fearful when others have it and when I have it as well. I've come to peace with it. Mainly, because of todays passage, but also because of learning how to constructively deal with it. 
I had a friend group in my twenties that was open to bringing up issues that bothered them. They taught me. As with anything, there is a learning curve. I learned to be self effacing, humble and to ask if I did anything to prompt the action. Most are open to this and a resolution can be found. Thus the anger is resolved.  
When I am angry I seek to process it. If I can't then I discuss it with others. If I can, I find an explanation. Sometimes it's a misunderstanding. Other times it's minute enough to forget. Some can discuss it with humor. 
Some aren't good with anger. Their rage is abusive, braking norms and boundaries. Some of these can be reasoned with and can learn. Others can't, thus I would distance myself from them. For these anger is sin. It's abusive and overboard. 
Some are angry people. Woe to those who are close to them. Some gravitate to them. It usually is the case that they were raised in that setting and learned to be oddly comfortable with it. If an abused person is rescued from an angry person, they would probably find another. 
Jesus was angry on occasion. It was with those that were corrupting temple worship and with those rulers who were spreading misinformation about God. He said in Mark 2:27, "Then Jesus declared, “The Sabbath was made for man, not man for the Sabbath." He said this to the pharisees who were complaining about Jesus' sabbath practices. 
Today's passage gives an end time with anger, a day. This doesn't mean that it's all resolved in a day, but that it's been prayed about and some sort of plan was made. Beyond this, the heat of anger destroys our souls and our health. 
God, thank You for this passage and the lessons Your Word teaches about anger.
