Jesus said one characteristic would set his people apart. “By this all people will know that you are my disciples, if you have love for one another” (John 13:35). But love for one another isn’t an automatic. It’s a determination, a conviction, a pursuit, a calling. It’s the kind of thing you must set your mind upon, orient your heart toward, stiffen your spine for. Love is what everyone wants. But love, it turns out, isn’t something everyone’s good at. Love for oneself comes naturally. Love for others is learned.
