…but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God. – 1 Corinthians 6:11

All disease in the body pollutes it in some way or other. Turn the microscope upon the affected part and you will soon discover that there is something obnoxious there! But sin in the soul pollutes terribly in the sight of God. There are quiet, respectable sins which men can conceal from their fellow creatures so that they can keep their place in society and seem to be all that they ought to be. But there are other sins which, like the leprosy of old, are white upon their brows! There are sins that are to be seen in the outward appearance of the man—his speech betrays him—his walk and conversation indicate what is going on within his heart. It is a dreadful thing for the sinner to remember that he is a polluted being—until he is washed in Christ’s precious blood, he is a being with whom God can have no sort of communion! Men have to put infected persons away from the society of other people. Under the Jewish Law, when men were in a certain stage of disease, they had to be isolated altogether from their fellow men and certainly could not come into the House of the Lord. O my Hearers, there are some of you, who, if your bodies were as diseased as your souls are, would not dare to show your faces in the streets! And some of us who have been washed in the blood of Jesus have felt ourselves to be so foul, so vile, so filthy, that if we could have ceased to exist, we would have welcomed annihilation as a gift!

I remember the time when, under a sense of sin, I was afraid to pray. I did groan out a prayer of a sort, but I felt as if the very earth must be weary of bearing up such a sinner—and that the stars in their courses must be anxious to shoot ominous fires upon the one who was so defiled! Perhaps some of you have felt as I did and now you join me in saying, “But we are washed! But we are sanctified! But we are justified in the name of the Lord Jesus and by the Spirit of our God!” The disease that was upon us was worse than the foulest leprosy, more infectious than the most terrible fever— causing greater deformity than the dropsy and working in us worse ills than the most foul disease that can ever fall upon the bodies of men! I would to God that men did but see that…it is most gracious on God’s part to treat them as diseased persons needing to be cured, rather than as criminals waiting to be executed! ~ C.H. Spurgeon
