And thus we find that, again, this elaborate ceremonial contains, not merely an instructive lesson in public sanitation, and practical suggestions in hygiene for our modern times; but also lessons, far more profound and momentous, concerning that spiritual malady with which the whole human race is burdened,--lessons therefore of the gravest personal consequence for every one of us. From among all diseases, leprosy has been selected by the Holy Ghost to stand in the law as the supreme type of sin, as seen by God! This is the very solemn fact which is brought before us in this chapter. Let us well consider it, and see that we receive the lesson, however humiliating and painful, in the spirit of meekness and penitence. Let us so study it that we shall with great earnestness and true faith resort to the true and heavenly High Priest, who alone can cleanse us of this sore malady. And in order to do this, we must carefully consider what is involved in this type. In the first place, leprosy is undoubtedly selected to be a special type of sin, on account of its extreme _loathsomeness_. Beginning, indeed, as an insignificant spot, "a bright place," a mere scale on the skin, it goes on spreading, progressing ever from worse to worse, till at last limb drops from limb, and only the hideous mutilated remnant of what was once a man is left. A vivid picture of the horrible reality has been given by that veteran missionary and very accurate observer, the Rev. William Thomson, D.D., who writes thus: "As I was approaching Jerusalem, I was startled by the sudden apparition of a crowd of beggars, sans eyes, sans nose, sans hair, sans everything.... They held up their handless arms, unearthly sounds gurgled through throats without palates,--in a word, I was horrified."[29] Too horrible is this to be repeated or thought of? Yes! But then all the more solemnly instructive is it that the Holy Spirit should have chosen this disease, the most loathsome of all, as the most fatal of all, to symbolise to us the true nature of that spiritual malady which affects us all, as it is seen by the omniscient and most holy God.
