Strange enough this regulation appears, yet there was wisdom in it, for the throwing out of the disease proved that the constitution was sound. This evening it may be well for us to see the typical teaching of so singular a rule. We, too, are lepers, and may read the law of the leper as applicable to ourselves. When a man sees himself to be altogether lost and ruined, covered all over with the defilement of sin, and in no part free from pollution; when he disclaims all righteousness of his own, and pleads guilty before the Lord, then he is clean through the blood of Jesus, and the grace of God. Hidden, unfelt, unconfessed iniquity is the true leprosy; but when sin is seen and felt, it has received its deathblow, and the Lord looks with eyes of mercy upon the soul afflicted with it. Nothing is more deadly than self-righteousness, or more hopeful than contrition. We must confess that we are "nothing else but sin," for no confession short of this will be the whole truth; and if the Holy Spirit be at work with us, convincing us of sin, there will be no difficulty about making such an acknowledgment - it will spring spontaneously from our lips.
