Thought from Today's Old Testament Passage:
We come now to another unusual section of this book, the section on leprosy. Someone may ask whether this is practical for today. May I say that all of this book is practical. We are in the section of the book which we have entitled "Holiness in Daily Life." God is concerned with the conduct of His children. We saw that He is concerned with their food; now in chapters 13, 14, and 15 we find He is concerned with leprosy and the cleansing of running issues.
Leprosy and running issues of the flesh are accurate symbols of the manifestation of sin in the heart of man. It shows the exceeding sinfulness of sin and the effect of sin in action. The emphasis of Leviticus is on sin.
In the heart of this book on worship of a holy God is this extended section on leprosy and issues in the flesh. The filthiness and repulsiveness of sin are represented in leprosy. The hopelessness and deadliness of sin are accurately portrayed. The leper who trudged down a hot, dusty, oriental road crying out, "Unclean! Unclean!" was a reminder to the Israelite that he, too, was a moral leper who needed supernatural cleansing.
Perhaps you are one of those who thinks that you will be saved by your works and that you don't need Christ as your Savior. May I say that if you could go to heaven just like you are, without Christ, you would go through heaven crying out, "Unclean! Unclean!" No angel would touch you with a twenty-foot pole. You couldn't come anywhere near the presence of God.
You see, man has the idea that he has some kind of claim on God, but we have no claim upon Him whatsoever. He owes us nothing. He could blot out of existence this little earth that we live on, and it would not even make a dent in this universe. But thank God, He loves us. I'm so glad He loves us! That is the only thing that could bind Him to us. (J. Vernon McGee, Thru the Bible Commentary [computer file], electronic ed., Logos Library System, (Nashville: Thomas Nelson), 1997 © 1981 by J.
