Ever feel overwhelmed by the Bible's command to love unconditionally? When people ask me, "How can I ever start to love everyone like I should?" I give the same answer I give those who ask how they can start jogging: Start slow, and then get slower! For the first week, the goal is "just to keep moving." Too many people buy new shoes and a fancy running suit and sprint out the door, eagerly chugging as hard as they can for about three blocks. Then their stomachs begin to ache, their muscles cramp, and their lungs burn. They wind up hitchhiking home exhausted, and gasp, "I will never do that again." That's called anaerobic (without oxygen) running. It's caused by a body using up more oxygen than it takes in. Many people try to run that way, and many people try to love that way. They love with great fervor and self-sacrifice, giving 100 percent but without the resources to continue for a lifetime. Down the road they find themselves in pain, gasping and cramped, saying, "I will never do that again." Love, like running, must be aerobic. Our output must be matched by our intake. Running requires oxygen. An enduring love requires God's word, his consolation, his presence. As we love aerobically, we'll build up our capacity to do more and more. And pretty soon we won't be huffing and puffing for half a mile; we'll be running marathons.
