Having witnessed the incredible power and infinite knowledge of Christ, Peter and his friends made the only proper response: they forsook all and followed Him. We know this was not their first encounter with Him, but it seems He had not yet called them to His permanent service. Probably they were already true believers, but the text seems to indicate that this is the point at which they became regular followers of the Lord, whithersoever He went.
Next in Luke’s account comes the story of the healing of the leper, who fell down at Jesus’ feet crying out, “Lord, if Thou wilt, Thou canst make me clean.” There is more wisdom in this little prayer of the leprous man than in a hundred great theological tomes. The leper recognizes and confesses Christ’s power, without manifesting even the shadow of a doubt. The question was not whether Christ was able, but whether He was willing. He had full confidence that the sovereign Lord could do according to His will in even the hardest of cases. This always ought to be the approach of sinners unto Christ. Not like the poor distressed father who said, “If Thou canst do anything,” but like the leper, who said, “If Thou wilt.”
To all such humble and sincere seekers the answer of Christ ever remains, “I will: be thou clean.” Our blessed Lord, in the infinity of His grace, never turns away a needy and desperate case who comes appealing to Him for mercy. Jesus put forth His hand to touch the leper, and expressed His willingness: “I will: be thou clean.” It has often been remarked that Christ here broke the provisions of the Mosaic law, which forbade any person from touching a leper. However, what we should recognize is that the power of Christ to heal and to cleanse was greater than the power of leprosy to contaminate. “Grace that is greater than all our sin” is the picture that is being drawn for us by the gospel artist. Rather than the leprosy polluting our Lord, so that He needed to go through the process of levitical cleaning, His divine power instantly healed the leper, making his skin fresh and clean like a child.
That the law was not meant to be dispensed with and thrown away is shown by Christ’s command that he delay not, but without telling anyone he should go to the priest and offer the gift that Moses had commanded, for a testimony to them. Once again, the picture of the power of the gospel is crystal clear in this instance of healing. When Christ has saved us, freeing us from the deadly pollution of sin, we should hasten to obey our God in all of His commandments, as a testimony of His grace to our fellow men.
