Spiritual Leprosy / Two Kinds of Doubt

Luke 5:12 While he was in one of the cities, there came a man full of leprosy. [11] And when he saw Jesus, he fell on his face and begged him, “Lord, if you will, you can make me clean.” 13 And Jesus [12] stretched out his hand and touched him, saying, “I will; be clean.” And immediately the leprosy left him. 14 And he charged him to tell no one, but “go and show yourself to the priest, and make an offering for your cleansing, as Moses commanded, for a proof to them.” 15 But now even more the report about him went abroad, and great crowds gathered to hear him and to be healed of their infirmities. 16 But he would withdraw to desolate places and pray.

Two points here:
1. Leprosy is such a powerful analogy of sin. Essentially, it causes the skin to lose sensation, to become numb to pain and pleasure, to die, as it were. This is the effect of our spiritual disease called sin. In our sinful flesh, we lose sensation for the "real" things of God's Kingdom. We are unable to sense when our hand is on the stove. We are unable to feel the loving touch of another. Eventually there is a complete breakdown of the body (read: spirit). Leprosy is incurable. The pragmatic solution is banishment, so the death of the sensations leads to the death of relationships. Sin divides us and is the antithesis of the Greatest Commandment which is true, whole, Kingdom community.
2. The second thing I get from this passage is two kinds of doubt - doubting God's goodness and doubting His power. In this case, the leper believes that Jesus is able to heal him, but isn't sure if he is willing. In other passages of the Bible we see individuals who believe Jesus is willing but not able. All of us fall into one of these two categories when we struggle with faith in God. We either doubt he is willing or doubt he is able to do what we ask. Maturity leads us to consider the possibility, with humility, that our requests may not be good requests. If this is the case, then it is certainly possible that he isn't willing to answer the request. But in the case of the leper, it is obvious that something which was created to be a certain way - the man's body - was in a state of disarray. God, as Creator and Maintainer of His creation, is in the business of setting things right - so he is certainly willing to heal the leper (both spiritually and physically). Doubting that he is able, on the other hand, comes down to a simple misunderstanding of God. We've all done that and will continue to do it because he is beyond the limits of our understanding. Job struggled with this (not seeing resolution to his agony) and was awakened to God's power when confronted by God himself. God makes it clear that he is able to do whatever he wants, which brings us back to the first doubt again. Why would God allow Job to suffer so much, to lose his family so tragically and go through so long a trial without any clear reassurance of love? Tough questions - and I am so grateful the writers of the Bible didn't shy away from them or pretend the answers were easy. It is something to bookmark and come back to again and again.
