Matthew 5:16

He means not that we should seek glory of men, but that though we conceal it, our work may shine forth in honour of God to those among whom we live.

Neither do men light a candle and put it under the bushel, but on the candlestick, and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in Heaven. For I, saith He, it is true, have kindled the light, but its continuing to burn, let that come of your diligence: not for your own sakes alone, but also for their sake, who are to profit by these rays, and to be guided unto the truth. Since the calumnies surely shall not be able to obscure your brightness, if you be still living a strict life, and as becomes those who are to convert the whole world. Show forth therefore a life worthy of His grace; that even as it is everywhere preached, so this light may everywhere accompany the same. Next He sets before them another sort of gain, besides the salvation of mankind, enough to make them strive earnestly, and to lead them unto all diligence. As thus, Ye shall not only, saith He, amend the world, if ye live aright, but ye will also give occasion that God shall be glorified; even as if ye do the contrary, ye will both destroy men, and make God's name to be blasphemed. And how, it may be asked, shall God be glorified through us, if at least men are to speak evil of us? Nay, not all men, and even they themselves who in envy do this, will in their conscience admire and approve you; even as the outward flatterers of such as live in wickedness do in mind accuse them. What then? Dost thou command us to live for display and vain glory? Far from it; I say not this; for I did not say, Give ye diligence to bring forward your own good deeds, neither did I say, Show them; but Let your light shine. That is, Let your virtue be great, and the fire abundant, and the light unspeakable. For when virtue is so great, it cannot lie hid, though its pursuer shade it over ten thousand fold. Present unto them an irreprehensible life, and let them have no true occasion of evil speaking; and then, though there be thousands of evil-speakers, no man shall be able to cast any shade upon you. And well did He say, your light, for nothing makes a man so illustrious, how manifold soever his will to be concealed, as the manifestation of virtue. For as if he were clad with the very sunbeam, so he shines, yet brighter than it; not spending his rays on earth, but surmounting also Heaven itself. Hence also He comforts them more abundantly. For, What though the slander pain you, saith He; yet shall ye have many to honor God on your account. And in both ways your recompence is gathering, as well because God is glorified through you, as because ye are defamed for God's sake. Thus, lest we should on purpose seek to be reproached, on hearing that there is a reward for it: first, He hath not expressed that sentiment simply, but with two limitations, namely, when what is said is false, and when it is for God's sake: and next He signifies how not that only, but also good report, hath its great profit, the glory of it passing on to God. And He holds out to them those gracious hopes. For, saith He, the calumny of the wicked avails not so much as to put all others in the dark, in respect of seeing your light. For then only when you have lost your savor shall they tread you under foot; but not when you are falsely accused, doing right. Yea, rather then shall there be many admiring, not you only, but for your sake your Father also. And He said not God, but your Father; already sowing beforehand the seeds of that noble birth, which was about to be bestowed upon them.

And Himself too, when He was making laws for His own disciples, what said He? "Do miracles, that men may see you"? By no means. But what? "Let your light shine before men, that they may see your good works, and glorify your Father which is in Heaven."
