For me, a good working definition of Christian Love (apapeo) toward our fellow man is . . .
To be committed and devoted to the physical, mental, emotional, and spiritual well-being of others.
I think this is easier to do if we can learn to not count people's wrongdoing against them. We can recognize the wrong, but not let it affect our actions, behaviours, and especially, our feelings and attitudes. That is, not let it affect us inappropriately. We may take some certain action, but let it be only in the Lord, not because of our own internal sense of outrage.
You may hurt me. I may take action against you. But let it be if it is good for you, not because I want to hurt back.
Love in Christ,
Mark
