Still, brethren, though the earth travels slowly, when compared with Mercury and Venus, yet, as Galileo said, it does move, and at a pretty good rate, too. I dare say, if you were to walk for twenty minutes, and you knew nothing about the speed at which the earth is traveling, you would be surprised if I assured you that you had in that short space of time gone more than 20,000 miles; but it would be a fact. This book, which has already given us much useful information, says: "It is a truly astonishing thought that, 'awake, asleep, at home, abroad,' we are constantly carried round with the terrestrial mass, at the rate of eleven miles a minute, and are, at the same time, traveling with it in space with a velocity of sixty-six thousand miles an hour. Thus, during the twenty minutes consumed in walking a mile from our thresholds, we are silently conveyed more than twenty thousand miles from one portion of space to another; and, during a night of eight hours' rest, or tossing to and fro, we are unconsciously translated through an extent equal to twice the distance of the lunar world." We do not take any notice of this movement, and so it is that little things, which are near and tangible, often seem more notable than great things which are more remote. This world impresses many men with far greater force than the world to come has ever done, because they look only upon the things that are seen and temporal. "But," perhaps you say, "we do not feel ourselves moving." No, but you are moving, although you are not conscious of it. So, I think that, sometimes, when a believer in Christ does not feel himself advancing in divine things, he need not fret on that account; I am not certain that those who imagine themselves to be growing spiritually are really doing so. Perhaps they are only growing a cancer somewhere; and its deadly fibers make them fancy there is a growth within them. Alas! so there is; but it is a growth unto destruction. When a man thinks that he is a full-grown Christian, he reminds me of a poor boy whom I used to see. He had such a splendid head for his body that he had often to lay it on a pillow, for it was too weighty for his shoulders to carry, and his mother told me that, when he tried to stand up, he often tumbled down, over-balanced by his heavy head. There are some people who appear to grow very fast, but they have water on the brain, and are out of due proportion; but he who truly grows in grace does not say, "Dear me! I can feel that I am growing; bless the Lord! Let's sing a hymn, 'I'm a-growing! I'm a-growing!'" I have sometimes felt that I was growing smaller, brethren; I think that is very possible, and a good thing, too. If we are very great in our own estimation, it is because we have a number of cancers, or foul gatherings, that need to be lanced, so as to let out the bad matter that causes us to boast of our bigness.
