A small boy came out of Sunday School and said to his father:
Daddy, we had a strange lesson today. It was about loving your enemies. But that’s ridiculous. How can you love your enemies? It’s absolutely impossible!
That we should love our enemies is a revolutionary teaching of Jesus, never heard before, and rarely taken seriously since. The small boy was right in a way: before Jesus, maybe it was impossible. But once Jesus said it, and lived it, to the point of death, it became possible for us.
