Jesus used anger for this. I think it was well thought out anger, the best kind. It is, for the most part, when we thoughtlessly and ruthlessly use anger that it is destructive. But, by making a friend and ally of our anger, it can become a great tool for growth and challenge, a way to help ourselves and others move to better places. It, sadly to say, is often the only way honesty abounds, perhaps if we could get more honest with our anger, and befriend it, instead of demonizing it, then we could be more honest.
Anger can be a catalyst for transformation, for creativity, and for new life.
Like any emotion, it can be abused. But while we are more willing to allow the abuse of love, envy, happiness, etc. And it certainly is not very appealing in the motorists we follow. But when I grew up I found that life handed you these rusty, bent old tools friendships, prayer, consciousness, honesty and said, Do the best you can with these, they will have to do. And mostly against all odds, they re enough.
