Now, I believe that, in like manner, there are two forces which are ever at work upon all of us, the one which draws us toward God, and the other which drives us away from him, and we are thus kept in the circle of life; but, for my part, I shall be very glad when I can pass out of that circle, and get away from the influence of the centrifugal force. I believe that, the moment I do so--as soon as ever the attraction which draws me away from God is gone--I shall be with him in heaven; that I do not doubt. Directly one or other of the two forces which influence human life shall be exhausted, we shall have either to drift away into the far-off space, through the centrifugal force--which God forbid!--or else we shall fly at once into the central orb, by the centripetal force, and the sooner that glorious end of life comes, the better will it be for us. With Augustine, I would say, "All things are drawn to their own center. Be thou the Center of my heart, O God, my Light, my only Love!" The sun himself is an enormous body; he has been measured, but I think I will not burden you with the figures, since they will convey to you no adequate idea of his actual size. Suffice it to say that, if the earth and the moon were put inside the sun, there would be abundance of room for them to go on revolving in their orbits just as they are now doing; and there would be no fear of their knocking against that external crust of the sun which would represent to them the heavens. It takes about eight minutes for light to reach us from the sun. We may judge of the pace at which that light comes when we reflect that a cannon-ball, rushing with the swiftest possible velocity, would take seven years to get there, and that a train, traveling at the rate of thirty miles an hour, and never stopping for refreshments, would require more than three hundred and fifty years before it would reach the terminus. You may thus form some slight idea of the distance that we are from the sun; and this, I think, furnishes us with a good illustration of faith. There is no man who can know, except by faith, that the sun exists. That he did exist eight minutes ago, I know, for here is a ray of light that has just come from him, and told me that; but I cannot be sure that he is existing at this moment. There are some of the fixed stars, that are at such a vast distance from the earth, that a ray of light from them takes hundreds of years to reach us; and, for aught we know, they may have been extinct long ago. Yet we still put them down in our chart of the heavens, and we can only keep them there by faith, for as, "through faith we understand that the worlds were framed by the Word of God," so it is only by faith that we can know that any of them now exist. When we come to examine the matter closely, we find that our eyesight, and all our faculties and senses, are not sufficient to give us positive conviction with regard to these heavenly bodies; and
