“The practical problem about charity (in our prayers) is very hard work, isn’t it? When you pray for Hitler & Stalin, how do you actually teach yourself to make the prayer real? The two things that help me are (a) A continual grasp of the idea that one is only joining one’s feeble little voice to the perpetual intercession of Christ, who died for those very men (b) A recollection, as firm as one can make it, of all one’s own cruelty wh. might have blossomed, under different conditions, into something terrible. You and I are not, at bottom, so different from these ghastly creatures” (C. S. Lewis, Letters of C. S. Lewis).
It’s one thing to pray for people who are diametrically opposed to you in their beliefs and lifestyle. It’s quite another to pray for those who are actively seeking to do you harm. I think the latter is what Jesus meant when He said to pray for your enemies.
I don’t think I could do that. At least, I know that in my own strength, I couldn’t. Only the power of the risen Christ dwelling in me could possibly love and pray for my enemies as they attack me. I believe that kind of supernatural power only comes in time of need, like it did for the disciple Stephen while he was being stoned to death with the approval of Saul. And later, it came to Saul, who now went by Paul, as he faced multiple attacks over proclaiming the death and resurrection of Jesus.
Ultimately, Jesus demonstrated praying for and loving your enemies best when He cried out to God, “Father, forgive them for they don’t know what they’re doing” as they were in the very act of murdering Him on the cross.
When I see that I am fundamentally no different than my enemies, it helps me to love them better. It helps me to see how much grace it took to save me when I’m not nearly as nice and good on my own as I had thought. It makes me that much more grateful to Jesus for saving me from me, and makes me less capable of hating anyone else.
