Loving Enough to be Angry

As a relative of mine continues to go through an awful situation, in which he is being wronged on a daily basis, I've struggled with how to be angry at unfairness without also harboring hatred. My "righteous indignation" so easily becomes plain old bitterness. So this week it was comforting, in a way, to come across this paragraph in Frederick Dale Bruner's excellent Commentary on the gospel of Matthew:
"The wrath of God is not the irritability of God; it is the love of God in friction with injustice. It is the warm, steady, patient, but absolutely fair grace of God in collision with manifest selfishness. God's wrath does not contradict God's love; it proves it. A love that pampers injustice is not lovable." (2nd edition, page 92).
As my family continues to find a way through all of this, may I continue to learn how to love as God does: generously, forgivingly, but still seeking justice and refusing to minimize wrong.
