5:14 Ye are the {f} light of the world. A city that is set on an hill cannot be hid.
(f) You shine and give light by being made partakers of the true light.
5:14 Ye are the light of the world. The business of the church is not only to save, but to enlighten. Christ is light, and his disciples must be light.
A city that is set on an hill. Anciently cities, for the sake of defense, were placed on hills. Such cities are seen from afar. So must the church give forth its light.
5:14 Ye are the light of the world - If ye are thus holy, you can no more be hid than the sun in the firmament: no more than a city on a mountain - Probably pointing to that on the brow of the opposite hill.
5:13-16 Ye are the salt of the earth. Mankind, lying in ignorance and wickedness, were as a vast heap, ready to putrify; but Christ sent forth his disciples, by their lives and doctrines to season it with knowledge and grace. If they are not such as they should be, they are as salt that has lost its savour. If a man can take up the profession of Christ, and yet remain graceless, no other doctrine, no other means, can make him profitable. Our light must shine, by doing such good works as men may see. What is between God and our souls, must be kept to ourselves; but that which is of itself open to the sight of men, we must study to make suitable to our profession, and praiseworthy. We must aim at the glory of God.
