“[...]mutual love consists in desiring what is good to another rather than to oneself, as with the love of parents towards children, and as with the love of those who are moved to do good not for their own benefit but because they find joy in doing it.” Secrets of Heaven 2738 ~ Swedenborg
I’m very enlightened by RoadGumby’s post, and DaveMSmith’s brief summary. Loving another is desiring and working for his good. I think we all agree that the one essential good for anyone is eternal salvation.
Just as parents don’t show love for their children by allowing them to do wrong and stupid things, Christians don’t show love for their enemies (or for anyone) by affirming sin or allowing destructive behavior, if it can reasonably be stopped.
