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.
Thus, you see, the telescope itself may be made to furnish us with many valuable illustrations. We may also turn to good account the lessons to be learned by the study of the stars for the purpose of navigation. The mariner, crossing the trackless sea, by taking astronomical observations, can steer himself with accuracy to his desired haven. Captain Basil Hall tells us, in the book I have previously mentioned, that "he once sailed from San Blas, on the West Coast of Mexico; and, after a voyage of eight thousand miles, occupying eighty-nine days, he arrived off Rio de Janeiro, having in this interval passed through the Pacific Ocean, rounded Cape Horn, and crossed the South Atlantic, without making land, or seeing a single sail except an American whaler. When within a week's sail of Rio, he set seriously about determining, by lunar observations, the position of his ship, and then steered his course by those common principles of navigation which may be safely employed for short distances between one known station and another. Having arrived within what he considered, from his computations, fifteen or twenty miles of the coast, he hove to, at four o'clock in the morning, to await the break of day, and then bore up, proceeding cautiously on account of a thick fog. As this cleared away, the crew had the satisfaction of seeing the great Sugar-Loaf Rock, which stands on one side of the harbor's mouth, so nearly right ahead that they had not to alter their course above a point in order to hit the entrance of the port. This was the first land they had seen for nearly three months, after crossing so many seas, and being set backward and forward by innumerable currents and foul winds. The effect upon all on board was electric; and, giving way to their admiration, the sailors greeted the commander with a hearty cheer."
In a similar manner, we also sail by guidance from the heavenly bodies, and we have for a long season no sight of land, and sometimes do not even see a passing sail; and yet, if we take our observations correctly, and follow the track which they point out, we shall have the great blessing, when we are about to finish our voyage, of seeing, not the great Sugar-Loaf Rock, but the Fair Haven of Glory right straight before us. We shall not have to alter our course even a single point; and, as we sail into the heavenly harbor, what songs of joy will we raise, not in glorification of our own skill, but in praise of the wondrous Captain and Pilot who has guided us over life's stormy sea, and enabled us to sail in safety even where we could not see our way!
Kepler makes a wise remark, when speaking about the mathematical system by which the course of a star could be predicted. After describing the result of his observations, and declaring his firm belief that the will of the Lord is the supreme power in the laws of nature, he says: "But if there be any man who is too dull to receive this science, I advise that, leaving the school of astronomy, he follow his own path, and desist from this wandering through the universe; and, lifting up his natural eyes, with which he alone can see, pour himself out in his own heart, in praise of God the Creator; being certain that he gives no less worship to God than the astronomer, to whom God has given to see more clearly with his inward eye, and who, for what he has himself discovered, both can and will glorify God."
That is, I think, a very beautiful illustration of what you may say to any poor illiterate man in your congregation: "Well, my friend, if you cannot comprehend this system of theology which I have explained to you, if these doctrines seem to you to be utterly incomprehensible, if you cannot follow me in my criticism upon the Greek text, if you cannot quite catch the poetical idea that I tried to give you just now, which is so charming to my own mind, nevertheless, if you know no more than that your Bible is true, that you yourself are a sinner, and that Jesus Christ is your Saviour, go on your way, and worship and adore, and think of God as you are able to do. Never mind about the astronomers, and the telescopes, and the stars, and the sun, and the moon; worship the Lord in your own fashion. Altogether apart from my theological knowledge, and my explanation of the doctrines revealed in the Scriptures, the Bible itself, and the precious truth you have received into your own soul, through the teaching of the Holy Spirit, will be quite enough to make you an acceptable worshiper of the Most High God."
I suppose you are all aware that among the old systems of astronomy was one which placed the earth in the center, and made the sun, and the moon, and the stars revolve around it. "Its three fundamental principles were the immobility of the earth, its central position, and the daily revolution of all the heavenly bodies around it in circular orbits."
Now, in a similar fashion, there is a way of making a system of theology of which man is the center, by which it is implied that Christ and his atoning sacrifice are only made for man's sake, and that the Holy Spirit is merely a great Worker on man's behalf, and that even the great and glorious Father is to be viewed simply as existing for the sake of making man happy. Well, that may be the system of theology adopted by some; but, brethren, we must not fall into that error, for, just as the earth is not the center of the universe, so man is not the grandest of all beings. God has been pleased highly to exalt man; but we must remember how the psalmist speaks of him: "When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou has ordained; what is man, that thou art mindful of him; and the son of man, that thou visitest him?" In another place, David says, "Lord, what is man, that thou takest knowledge of him! or the son of man, that thou makest account of him! Man is like to vanity: his days are as a shadow that passeth away." Man cannot be the center of the theological universe; he is altogether too insignificant a being to occupy such a position, and the scheme of redemption must exist for some other end than that of merely making man happy, or even of making him holy. The salvation of man must surely be first of all for the glory of God; and you have discovered the right form of Christian doctrine when you have found the system that has God in the center, ruling and controlling according to the good pleasure of his will. Do not dwarf man so as to make it appear that God has no care for him; for if you do that, you slander God. Give to man the position that God has assigned to him; by doing so, you will have a system of theology in which all the truths of revelation and experience will move in glorious order and harmony around the great central orb, the Divine Sovereign Ruler of the universe, God over all, blessed forever.
You may, however, any one of you, make another mistake by imagining yourself to be the center of a system. That foolish notion is a good illustration, I think. There are some men whose fundamental principles are, first of all, their own immobility: what they are, they always are to be, and they are right, and no one can stir them; secondly, their position is central, for them suns rise and set, and moons do wax and wane. For them their wives exist; for them their children are born; for them everything is placed where it appears in God's universe; and they judge all things according to this one rule, "How will it benefit me?" That is the beginning and the end of their grand system, and they expect the daily revolution, if not of all the heavenly bodies, certainly of all the earthly bodies around them. The sun, the moon, and the eleven stars are to make obeisance to them. Well, brethren, that is an exploded theory so far as the earth is concerned, and there is no truth in such a notion with reference to ourselves. We may cherish the erroneous idea; but the general public will not, and the sooner the grace of God expels it from us, the better, so that we may take our proper position in a far higher system than any of which we can ever be the center.
The Sun, then, not the earth, is the center of the solar system; which system, mark you, is probably only one little insignificant corner of the universe, although it includes such a vast space that if I could give you the actual figures you would not be able to form the slightest idea of what they really represented. Yet that tremendous system, compared with the whole of God's universe, may be only like a single grain of dust on the sea-shore, and there may be myriads upon myriads of systems, some of which are made up of innumerable systems as large as ours, and the great sun himself may only be a planet revolving round a greater sun, and this world only a little satellite to the sun, never yet observed by the astronomers who, it may be, live in that remoter sun still farther off. It is a marvelous universe that God has made; and however much of it we may have seen, we must never imagine that we have discovered more than a very small portion of the worlds upon worlds that God has created.
