Matthew 10:26
. Fear them not therefore When the apostles saw the gospel so greatly despised, and recollected the small number of believers, they might be apt to throw away hope even for the future. Christ now meets this doubt, by declaring that the gospel would be widely spread, would at length rise superior to all the hindrances which might arise from men, and would become generally known. The saying, nothing is covered that shall not be revealed, has some appearance of being a proverb: but we restrict it in a special manner to the doctrine of salvation, which Christ promises will be victorious, whatsoever may be the contrivances of men to oppose it. Though he sometimes preached openly in the temple, yet, as his doctrine was rejected, it was still concealed in dark comers: but he declares that the time for proclaiming it will come; which, we know, happened shortly afterwards. In no part of the earth was there ever such thunder heard as the voice of the gospel, which resounded through the whole world. As this promise ought to fill them with courage, Christ exhorts them to devote themselves to it with boldness and perseverance, and not to be alarmed, though they see the gospel hitherto despised, but, on the contrary, to become its zealous preachers.
The passage which I have taken from Mark was, perhaps, spoken at a different time, and in a different sense: but as the sentences in that place are concise, I have followed the meaning which appeared to me the most probable. After having commanded the apostles to assemble burning lamps by sending out a bright light to a great distance, he immediately afterwards adds, nothing is hidden which shall not be revealed. Now the lamp of the gospel was kindled by the apostles, as it were in the midst of darkness, that by their agency it might be raised on high, and shine throughout the whole world. The passage in the eighth chapter of Luke’s Gospel is precisely alike. As to the passage in the twelfth chapter, there is no room to doubt that it has the same meaning, though there is a difference in the words: for Christ there commands the apostles to bring to light what they had spoken in darkness. This means, that hitherto they had only spoken in whispers about the gospel, but that their future preaching would be so public, that it would spread to the most distant parts of the world.
