8:3 Touched him... immediately his leprosy was cleansed. To touch a leper was forbidden, and carried ceremonial defilement, but at the touch of Jesus the source of the defilement fled, and the leper was clean. At the touch of Jesus all impurity flees.
8:2-4 In these verses we have an account of Christ's cleansing a leper, who came and worshipped him, as one clothed with Divine power. This cleansing directs us, not only to apply to Christ, who has power over bodily diseases, for the cure of them, but it also teaches us in what manner to apply to him. When we cannot be sure of God's will, we may be sure of his wisdom and mercy. No guilt is so great, but there is that in Christ's blood which atones for it; no corruption so strong, but there is that in his grace which can subdue it. To be made clean we must commend ourselves to his pity; we cannot demand it as a debt, but we must humbly request it as a favour. Those who by faith apply to Christ for mercy and grace, may be sure that he is freely willing to give them the mercy and grace they thus seek. And those afflictions are blessed that bring us to know Christ, and cause us to seek help and salvation from him. Let those who are cleansed from their spiritual leprosy, go to Christ's ministers and open their case, that they may advise, comfort, and pray for them.
