+III. God's voice of wisdom has been uttered where men could hear it.+ Wisdom uttereth her voice "in the streets," "in the chief places of concourse," "in the gates." The merchant brings his silks and diamonds to the crowded cities, because in them he is most likely to find purchasers. The vendors of goods seek the broad thoroughfares, because there they find streams of human beings to whom they offer their wares. God has observed this method in offering His Divine wisdom to the sons of men. The highest wisdom of God--the Gospel--was first proclaimed in the city of Jerusalem, at a time when there were gathered there men "out of every nation under heaven" (Acts ii. 5). The apostles of Christ preached in the chief cities of the civilised world, in Corinth, Athens, Antioch, Ephesus, and Rome. And now the voice of wisdom cried in the principal centres of the population of the world. The fishermen spread their nets where most fish congregate, and the fishers of men are attracted to the places where most human souls are gathered. +IV. God's voice of wisdom addresses all classes of sinners.+ 1. _The simple ones._ The unwary and those easily misled. Some men sin through ignorance or through the influence of others. As the unwalled garden is open to the foot of every dog that passes by, so the man who has no principle of his own to defend him is liable to have his soul entered and taken possession of by the first tempter who passes by. 2. _The scorner._ He is a sinner of a deeper dye. The child who is indifferent to his good father's love and the attractions of his happy home is a sinner, but the son who mocks his parents and holds up their words to ridicule is certainly a greater sinner. The simple man denotes a sinner who is passive in the hands of evil, but the scorner is active against good. He is placed before us in Holy Scripture as one who has reached the climax of human iniquity (Psa. i. 1). 3. _Fools are addressed._ The man who would rather use means to increase his disease than seek to cure it, may very properly be called a fool. The blind man who chooses to remain blind when he might be healed is certainly a fool. And certainly this is an appropriate name for those who love moral darkness rather than light. He who hates the knowledge which would save him and prefers death to life is the most unwise man upon the face of God's earth. +V. Although sinners may differ in degree, the same reproof and invitation are addressed to all.+ A rich man may be able to satisfy the wants of a hungry multitude, although all may not be equally hungry. If a physician possesses remedies which can heal men whose disease is deeply rooted, he will be able to cure those upon whom it has as yet a lighter hold. The voice of God to men offers but one way of satisfaction and soul-healing, viz., _repentance_. "Turn ye at my reproof." And the gift of His Spirit which accompanies repentance (Acts ii. 38) is powerful to change the greatest sinner into a saint.
