What is the biggest spiritual problem in the world? It’s exactly the same as the biggest problem in Bible times. Doing good. Or, more precisely, doing good for salvation. It’s the biggest spiritual problem because doing cannot be done. It’s not just that we cannot do enough good; we simply cannot do any good (Romans 3:12). But that doesn’t stop most from trying. How do we solve the massive problem that doing does nothing? Jesus has a surprising answer for us in Luke 10:25-37.
