If you’ve ever wondered what belief really means, it’s simply another word for faith. And faith is what sustains us in the Christian life. Life isn’t a sprint—it’s a marathon. Anyone who has run a marathon knows about “the wall.” For most, it comes around mile 18 or 20. A marathoner trains for months, but no matter how prepared, everyone eventually hits the wall. Physically, it’s when your body runs out of stored energy—glycogen in your muscles and liver—and moving forward feels impossible.

If you’ve never run a marathon before, hitting mile 18, 19, or 20 might make you think, “I can’t possibly go another six miles.” So, reaching the wall and realizing there are still miles to go can feel overwhelming. What gets a person through isn’t just training, but the belief that they can push past the wall. Every marathoner knows the wall is coming—they may not know exactly when, but they recognize it as soon as it hits. That’s the moment when they must dig deep and trust what they know to be true, even as their body screams, “I don’t feel good,” “this isn’t good for you,” “stop,” or “this isn’t possible for someone like me.”

My friend, every runner hits a wall at some point. Marathoners trust what is written: the wall will come, but you have what you need to finish. The same is true in life. If you’re facing a wall right now, remember—you have what it takes to keep going. Faith in God doesn’t make things easy, but it does make every victory possible.
