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. The earth, and all the planets, and all the solid matter of the universe, are controlled, as you know, by the force of attraction. We are kept in our place in the world, in going round the sun, by two forces, the one called centripetal, which draws us toward the sun, and the other called centrifugal, which is generally illustrated by the tendency of drops of water on a trundled mop to fly off at a tangent from the circle they are describing.
