We always fail when we judge of the fate of others. Life is double—an internal and an external life; the latter often open to the eyes of all, the former only seen by the eye of God. Nor is it alone those material things which we conceal from the eyes of others, which often make the apparently splendid lot in reality a dark one, or that which seems sad or solitary, cheerful and light within. Our characters, our spirits operate upon all that fate or accident subjects to them. We transform the events of life for our own uses, be those uses bitter or sweet; and as a piece of gold loses its form and solidity when dropped into a certain acid, so the hard things of life are resolved by the operations of our own minds into things the least resembling themselves. True, a life of study and of thought may seem to most men a calm and tranquil state of existence. Such pursuits gently excite, and exercise softly and peacefully the highest faculties of the intellectual soul; but age brings with it indifference even to these enjoyments—nay, it does more, it teaches us the vanity and emptiness of all man’s knowledge. We reach the bounds and barriers which God has placed across our path in every branch of science, and we find, with bitter disappointment, at life’s extreme close, that when we know all, we know nothing. This I have learned, and it is all that I have learned in eighty years, that the only knowledge really worth pursuing is the knowledge of God in his word and his works—the only practical application of that high science, to do good to all God’s creatures. * * * * *
