From a book[2] to which I am indebted for many quotations in this lecture, I learn that the telescope was discovered in this singular manner: "A maker of spectacles at Middleburg stumbled upon the discovery owing to his children directing his attention to the enlarged appearance of the weathercock of a church, as accidentally seen through two spectacle-glasses, held between the fingers some distance apart. This was one of childhood's inadvertent acts; and seldom has there been a parallel example of mighty results springing out of such a trivial circumstance. It is strange to reflect upon the playful pranks of boyhood being connected in their issue, and at no distant date, with enlarging the known bounds of the planetary system, resolving the nebula of Orion, and revealing the richness of the firmament." In a similar way, a simple incident has often been the means of revealing to men the wonders of divine grace. What a certain individual only meant to be trifling with divine things, God has overruled for his soul's salvation. He stepped in to hear a sermon as he might have gone to the theater to see a play; but God's Spirit carried the truth to his heart, and revealed to him the deep things of the kingdom, and his own personal interest in them. [2] "The Heavens and the Earth," by Thomas Milner, M. A., F. R. G. S. I think that incident of the discovery of the telescope might be usefully employed as an illustration of the connection between little causes and great results, showing how the providence of God is continually making small things to be the means of bringing about wonderful and important revolutions. It may often happen that what seems to us to be a matter of pure accident, with nothing at all notable about it, may really have the effect of changing the entire current of our life, and it may be influential also in turning the lives of many others in quite a new direction. When once the telescope had been discovered, then the numbers and position and movements of the stars became increasingly visible, until at the present time we are able to study the wonders of the stellar sky, and continually to learn more and more of the marvels that are there displayed by the hand of God. The telescope has revealed to us much more of the sun, and the moon, and the stars than we could ever have discovered without its aid. Dr. Livingstone, on account of his frequently using the sextant when he was traveling in Africa, was spoken of by the natives as the white man who could bring down the sun, and carry it under his arm. That is what the telescope has done for us, and that is what faith in the gospel has done for us in the spiritual heavens; it has brought down to us the Father, the Son, and the Holy Spirit, and given us the high eternal things to be our present possession and our perpetual joy.
