13 'Ye are the salt of the land, but if the salt may lose savour, in what shall it be salted? for nothing is it good henceforth, except to be cast without, and to be trodden down by men.
14 'Ye are the light of the world, a city set upon a mount is not able to be hid; 15 nor do they light a lamp, and put it under the measure, but on the lamp-stand, and it shineth to all those in the house;

Commentary on Matthew 5:13-16
(Read Matthew 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.
