Matthew 8:2

Secondly, the infirm man is introduced, and two things are done: first, the infirmity is named; secondly, concern is showed. The infirmity is leprosy, which signifies spiritual infirmities. For some infirmities are within, as fevers; but some, even though from within, show outward symptoms, as …

(ubi sup.) He works the cures below, and does none in the mount; for there is a time for all things under heaven, a time for teaching, and a time for healing. On the mount He taught, He cured souls, He healed hearts; which being finished, as He came down from the heavenly heights to heal bodies, there came to Him a leper and made adoration to Him; before he made his suit, he began to adore, showing his great reverence. (ubi sup.) Lord, by Thee all things were made, Thou therefore, if thou will, canst make me clean. Thy will is the work, and all works are subject to Thy will. Thou of old cleansedst Naaman the Syrian of his leprosy by the hand of Elisha, and now, if thou will, thou canst make me clean.

"When He was come down from the mountain, great multitudes followed Him. And, behold, a leper approached and fell prostrate before Him, saying, Lord, if Thou wilt, Thou canst make me clean." Being a man of good sense, the leper did not go up on …

A leper came - Leprosies in those countries were seldom curable by natural means, any more than palsies or lunacy. Probably this leper, though he might not mix with the people, had heard our Lord at a distance.

And behold there came a leper,....

This is fitly recorded with the first of Christ's miracles, 1. Because the leprosy was looked upon, among the Jews, as a particular mark of God's displeasure: hence we find Miriam, Gehazi, and Uzziah, smitten with leprosy for some one particular sin; and therefore Christ, to show that he came to turn away the wrath of God, by taking away sin, began with the cure of a leper.

And, behold, there came a leper - The leprosy λεπρα, from λεπις, a scale, was an inveterate cutaneous disease, appearing in dry, thin, white scurfy scales or scabs, either on the whole body, or on some part of it, usually attended with violent itching, and often with great pain. The eastern leprosy was a distemper of the most loathsome kind, highly contagious, so as to infect garments, (Lev 13:47, etc)., and houses, (Lev 14:34, etc)., and was deemed incurable by any human means.

The eighth chapter of St. Matthew’s Gospel is full of our Lord’s miracles: no less than five are specially recorded. There is beautiful fitness in this. It was fitting that the greatest sermon ever preached should be immediately followed by mighty proofs that the preacher was the Son of God. Those who heard the Sermon on the Mount would be obliged to confess that as “none spake such words as this man,” so also no one did such works.

But one thing he was sure of, that He had but to "will" it. This shows with what "worship" of Christ this leper fell on his face before Him. Clear theological knowledge of the Person of Christ was not then possessed even by those who were most with Him and nearest to Him.

MATTHEW has placed this miracle immediately after the sermon on the mount. In all probability some little time intervened in which our Lord had preached at Capernaum and had also healed the people in the street, as we read just now in the first chapter of Mark. It was not the object of Matthew to arrange his facts precisely in the order of time—he had another end in view. After the sermon on the mount he gives us remarkable miracles, as if to teach us that our Lord's Words were confirmed by His works.

The eighth chapter of St. Matthew’s Gospel is full of our Lord’s miracles: no less than five are specially recorded. There is beautiful fitness in this. It was fitting that the greatest sermon ever preached should be immediately followed by mighty proofs that the preacher was the Son of God. Those who heard the Sermon on the Mount would be obliged to confess that as “none spake such words as this man,” so also no one did such works. The verses we have now read contain three great miracles: a leper is healed with a touch, a palsied person is made well by a word, a woman sick with a fever is restored in a moment to health and strength. On the face of these three miracles we may read three striking lessons. Let us examine them and lay them to heart. Let us learn for one thing how great is the power of our Lord Jesus Christ. Leprosy is the most fearful disease by which man’s body can be afflicted. He that has it is like one dead person while he lives; it is a complaint regarded by physicians as incurable (see 2 Kings 5:7 ). Yet Jesus says, “Be thou clean!” and immediately the leprosy was cleansed.” To heal a person of the palsy without even seeing him, by only speaking a word, is to do that which our minds cannot even conceive: yet Jesus commands, and at once it is done. To give a woman prostrate with a fever, not merely relief, but strength to do work in an instant, would baffle the skill of all the physicians on earth: yet Jesus “touched” Peter’s wife’s mother and “she arose and ministered unto them. These are the doings of one that is almighty. There is no escape from the conclusion. This was “the finger of God” ( Exodus 8:19 ). Behold here a broad foundation for the faith of a Christian.

It was not the object of Matthew to arrange his facts precisely in the order of time—he had another end in view. After the sermon on the mount he gives us remarkable miracles, as if to teach us that our Lord's Words were confirmed by His works. Our Lord was mighty both in word and deed. His kingdom comes not only with truth, but with power. He worked miracles that men might see with their eyes that the power of God was upon Him and might know that He spoke with Divine authority. At this day, Beloved, it is even so. Power goes forth with the preaching of the Gospel. The Words of the Lord Jesus are spirit and life—they are in themselves full of authority and we ought to accept them with ready faith—but since we are slow to believe, the Lord continues to work as well as speak. The "signs following" are still to be perceived—blind eyes are opened, deaf ears are unstopped, hearts of stone are turned to flesh and the dead in sin are quickened. Conversion by Divine Grace follows the proclamation of the Doctrines of Grace, for the Word of God is with power. Beloved, we have beheld wonders of regenerating power in our own midst and therefore we are bound to believe in Jesus more and more. Blessed be the Divine power which confirms the Word! Jesus is never known in the full authority of His Word until the Holy Spirit makes us feel the glory of His work within our hearts. We have the Word and we pray for more of the work. The Lord speaks to us graciously in the Gospel ministry. Oh, that He would now work with us, also, to His own glory! When our Lord spoke, His Words were winged in such a way that they flew far afield.

There came a leper - No disease with which the human family has been afflicted has been more dreadful than that which is often mentioned in the Bible “as the leprosy.” It first exhibits itself on the surface of the skin. The appearance is not always the same, but it commonly resembles the spot made by the puncture of a pin or the pustules of a ringworm. The spots generally make their appearance very suddenly. Perhaps its appearance might be hastened by any sudden passion, as fear or anger. See Num 12:10; 2Ch 26:19. The spots commonly exhibit themselves at first on the face, about the nose and eyes, and increase in size a number of years, until they become as large as a pea or a bean. There are three kinds of leprosy, distinguished by the appearance of the spots - the white, the black, and the red leprosy. These spots, though few at first, gradually spread until they cover the whole body. But, though the “appearance” of the disease is at first in the skin, yet it is deeply seated in the bones, and marrow, and joints of the body. We have reason to suppose that in children it is concealed in the system for a number of years until they arrive at the age of puberty; and in adults for three or four years, until at last it gives fearful indications on the skin of its having gained a well-rooted and permanent existence. A leprous person may live twenty, or thirty, or even fifty years, if he received the disease at his birth, but they will be years of indescribable misery. The bones and marrow are pervaded with the disease. The malady advances from one stage to another with slow and certain ruin. “Life still lingers amid the desolation;” the joints, and hands, and feet lose their power; and the body “collapses,” or falls together in a form hideous and awful.

Was Jesus willing? You will never find Jesus missing an opportunity of doing good. You will find that He is always more willing to work than we are to give Him an opportunity to work.
