Matthew 5:14-16 "You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works and glorify your Father in heaven."
Commentary: Commentary: "1. As the lights of the world, they are illustrious and conspicuous, and have many eyes upon them. A city that is set on a hill cannot be hid. The disciples of Christ, especially those who are forward and zealous in his service, become remarkable, and are taken notice of as beacons. They are for signs (Isa. 7:18), men wondered at (Zec. 3:8); all their neighbours have any eye upon them. Some admire them, commend them, rejoice in them, and study to imitate them; others envy them, hate them, censure them, and study to blast them. They are concerned therefore to walk circumspectly, because of their observers; they are as spectacles to the world, and must take heed of every thing that looks ill, because they are so much looked at. The disciples of Christ were obscure men before he called them, but the character he put upon them dignified them, and as preachers of the gospel they made a figure; and though they were reproached for it by some, they were respected for it by others, advanced to thrones, and made judges (Lu. 22:30); for Christ will honour those that honour him.
2. As the lights of the world, they are intended to illuminate and give light to others (v. 15), and therefore,
(1.) They shall be set up as lights. Christ has lighted these candles, they shall not be put under a bushel, not confined always, as they are now, to the cities of Galilee, or the lost sheep of the house of Israel, but they shall be sent into all the world. The churches are the candlesticks, the golden candlesticks, in which these lights are placed, that they light may be diffused; and the gospel is so strong a light, and carries with it so much of its own evidence, that, like a city on a hill, it cannot be hid, it cannot but appear to be from God, to all those who do not wilfully shut their eyes against it. It will give light to all that are in the house, to all that will draw near to it, and come where it is. Those to whom it does not give light, must thank themselves; they will not be in the house with it; will not make a diligent and impartial enquiry into it, but are prejudiced against it.
(2.) They must shine as lights,
[1.] By their good preaching. The knowledge they have, they must communicate for the good of others; not put it under a bushel, but spread it. The talent must not be buried in a napkin, but traded with. The disciples of Christ must not muffle themselves up in privacy and obscurity, under pretence of contemplation, modesty, or self-preservation, but, as they have received the gift, must minister the same, Lu. 12:3.
[2.] By their good living. They must be burning and shining lights (Jn. 5:35); must evidence, in their whole conversation, that they are indeed followers of Christ, James 3:13. They must be to others for instruction, direction, quickening, and comfort, Job 29:11."
