As my friends and relations know, I yield to no one when it comes to harbouring resentment and nursing grudges.
Which is why this post by the Anchoress hit one out of the park today. Loving your enemies is truly where the rubber hits the road for us Christians. It is also the hardest thing for me to do, by a long shot.
The problem is that you can not just say, once, "I forgive" and move on. The loser who unjustly vilified my wife still causes flashes of extreme anger in me, and she has been retired now for three years. Letting go the blind fury, not giving into it, is easily the hardest thing I have ever had to do. Even though it is the right thing to do.
