Anger is useful to the holder, as it restructures a protective spirit. It is your soul fighting for the right, or fighting to be righted, once again.
The danger is to those with whom you share life, for anger can spill out of your container into theirs with unintended consequences.
Consider this:
Be angry until your anger is spent. Don't leave any behind to congeal into bitterness.
Freedom is spent anger--when spent in the presence of the Lord--for He alone can hold it for you.
Be angry at Him, with Him, but not away from Him. Your anger in His presence is your compass back to freedom.Anger is a God-given segment of our spirit.
Transform it into the useful tool that it is by waging it with the power and in the presence of God.
