When we contemplate these three classes of human beings, we perceive that only one of them can be said to lead successful lives. Two classes, and both of them painfully numerous, fail. The question rises to the mind with fearful solemnity, were they created for this end,--created to fail? Can we for a single moment believe that a Father of infinite justice and mercy ever created one individual among his children, an accountable being, neither insane nor idiotic, and yet so imperfect that he _must_ fail? Surely it were blasphemy to hold such an act possible. Infinitely various are the works of his hand in the forms of humanity, as in every other department of the universe, but even so manifold are the varieties and degrees of service which he prepares for every one to do. There is a place and a use for every one, and whoever fails of finding a place and a use fails, not because he was created incompetent, but because he refuses to cultivate the powers wherewith he is endowed. Indolence and selfishness, the moth and rust of Character, are corroding and devouring the delicate organization of the internal man, which can retain the wholeness and brightness of its powers only by constant use. We are weak and useless, not because we were created to be so, but because we do not listen to the voice of conscience when it tells us to serve the Lord with _all_ our strength, in the very place where we now are, and at the very time that now is. It is not because the power of growth is not in them that our talents do not multiply, but because we fold them in a napkin of indifference, and bury them in the earth of our lower nature. Understanding and Affection are within us all, and if they do not develop into a life of use, into a Character that will fit us for heaven,--and this is what we should always keep before our minds as the only genuine success,--it is because we have not striven as we might and ought. Understanding and Affection are within us all, differing, not in kind, but only in degree; and they are constantly at work, involuntarily if we do not voluntarily assume their control. In the little child they work as involuntarily as the heart beats and the lungs respire; but so soon as the child is old enough to begin to know the difference between right and wrong, the action of these powers should begin to be voluntary; should begin to be under the guidance of conscience.
