" Out of that union [Kingdom of God reign] we discover love as a life power that has the marvelous, many-sided expression spelled out by Paul in 1 Corinthians 13. But this beautiful statement by Paul is commonly misunderstood in exactly the same legalistic way as is Jesus' Discourse on the Hill. Love, Paul there tells us, is patient, kind, free of jealousy and arrogance, is not rude or self-seeking, is not easily angered and keeps no record of wrongs, takes no joy in things that are wrong but instead in what is true. It always protects, always accepts, always hopes, and endures everything. And it never quits (1 Cor. 13:4–8). People usually read this, and are taught to read it, as telling them to be patient, kind, free of jealousy, and so on—just as they read Jesus' Discourse as telling them to not call others fools, not look on a woman to lust, not swear, to go the second mile, and so forth. But Paul is plainly saying—look at his words—that it is love that does these things, not us, and that what we are to do is to “pursue love” (1 Cor. 14:1). As we “catch” love, we then find that these things are after all actually being done by us. These things, these godly actions and behaviors, are the result of dwelling in love. We have become the kind of person who is patient, kind, free of jealousy, and so on. Paul's message is exactly the same as Jesus' message. And no wonder, for as Paul was always the first to say, he learned what he taught from Jesus (Gal. 1:12). "
