It is easy to be alarmed and even angry at sin that we see around us. Even Jesus was angry at sin and its consequences in the world. But His anger did not fall into the category of the wrath of man which never brings about the righteousness of God. A primary weakness of our anger is that we do not channel our anger into prayer for God to work mightily as He alone can work.
Often our expression of anger is a statement of unbelief. We have more faith in our own ability to change hearts and situations than we do in God who may be at work unseen around us.
Let your anger drive you to your knees, in prayer.
