This responsibility it was impossible to avoid. As a matter of course, the kingdom of heaven must be a prominent object in the sight of men. The mountain of the Lord's house must be established on the top of the mountains (Isa. ii. 2), and therefore may not be inconspicuous: "A city set on a hill cannot be hid." It has been often said, but it will bear repeating, that Christians are the world's Bible. People who never read a word of either Old or New Testament will read the lives of those who profess to draw their inspiration thence, and will judge accordingly. They will form their opinions of Christ and of His kingdom by those who call themselves or are called by others Christians. "A city set on a hill _cannot_ be hid." Here we have a truth complementary to that other conveyed in the symbol of salt. It taught that true Christians exert a great deal of silent, unobserved influence, as of salt hidden in a mass; but, besides this, there is their position as connected with the kingdom of heaven which forbids their being wholly hid.
Indeed, it is their duty to see to it that they are not artificially hid: "Neither do men light a lamp, and put it under the bushel, but on the stand; and it shineth unto all that are in the house" (R.V.). How beautifully does the illustration lend itself to the needed caution against timidity, without giving the least encouragement to the opposite vice of ostentation! Why does light shine? Simply because it cannot help it; it is its nature; without effort or even consciousness, and making no noise, it quietly does its duty; and in the doing of it does not encourage but even forbids any looking at itself--and the brighter it is, the more severely does it forbid it. But while there is no ostentatious obtrusiveness on the one hand, there is no ignoble shirking on the other. Who would ever think of kindling a light and then putting it under a bed? Yet how many Christians do that very thing when they are called to work for Christ, to let the light He has given them shine in some of the dark places where it is most needed!
Here, again, our Lord lays His finger on a weak spot. The Church suffers sorely, not only from quantities of savourless salt,--people calling themselves Christians who have little or nothing distinctively Christian about them,--but also from bushel-covered lights, those who are genuinely Christian, but who do all they can to hide it, refusing to speak on the subject, afraid to show earnestness even when they feel it most, carefully repressing every impulse to let their light shine before men, doing everything, in fact, which is possible to render their testimony to Christ as feeble, and their influence as Christians as small, as it can be. How many in all our Christian communities are constantly haunted by a nervous fear lest people should think them forward! For one person who makes a parade of his Christianity there are a hundred or a thousand who want always to shrink into a corner. This is not modesty; it is the sign of an unnatural self-consciousness. The disciples of Christ should act simply, naturally, unconsciously, neither making a display on the one hand nor hiding their light on the other. So the Master puts it most beautifully and suggestively: "Let your light so shine before men, that they may see your good works" (not the worker--that is of no consequence--but the works), "and glorify your Father which is in heaven."
So closes the first great division of the Manifesto of the King. It had begun with "goodwill to men"; it has shown the way of "peace on earth"; it closes with "glory to God in the highest." It is a prolonged echo of the angels' song. The Gospel of the Kingdom, not only as set forth here in these beautiful paragraphs, but in all its length and breadth and depth and height, in all its range and scope and application, is but an expansion of its very first proclamation: "Glory to God in the highest, on earth peace, goodwill to men."
