I know that we are not, all the while, thinking of any theory of life. So neither are we all the while thinking of the laws of nature; the attraction of gravitation, for instance. But unless there were some ultimate reference to laws, both material and moral, our minds would lose their balance and security. If I believed that the hill by my side, or the house I live in, were liable any moment to be unseated and hurled through the air by centrifugal force, I should be ill at ease. And if I believed that the world was made by a malignant Power, or that the fortunes of men were the sport of a doubtful conflict between good and evil deities or principles, my life, like that of the ancients, would be filled with superstitions and painful fears. The foundation of all rational human tranquillity, cheerfulness, and courage, whether we are distinctly conscious of it or not, lies in the ultimate conviction, that God is good,--that his providence, his order of things in the world, is good; and theology, in the largest sense of the term, is as vital to us as the air we breathe. If, then, I thought that this world were a castoff, or a wrecked and ruined, world; if I thought that the human generations had come out from the dark eclipse of some pre-existent state, or [124] from the dark shadow of Adam's fall, broken, blighted, accursed, propense to all evil, and disabled for all good; and if, in consequence, I believed that unnumbered millions of ignorant heathens, and thousands around me,--children but a day old in their conscious moral probation, and men, untaught, nay, ill-taught, misled and blind,--were doomed, as the result of this life-experiment, to intense, to unending, to infinite pain and anguish,--most certainly I should be miserable in such a state, and nothing could make life tolerable to me. Most of all should I detest myself, if the idea that I was to escape that doom could assuage and soothe in my breast the bitter pain of all generous humanity and sympathy for the woes and horrors of such a widespread and overwhelming catastrophe. What, then, do I say and think? I say, and I maintain, that the constitution of the world is good, and that the constitution of human nature is good; that the laws of nature and the laws of life are ordained for good. I believe that man was made and destined by his Creator ultimately to be an adoring, holy, and happy being; that his spiritual and physical constitution was designed to lead to that end; but that end, it is manifest from the very nature of the case, can be attained only by a free struggle; and this free struggle, with its mingled success and failure, is the very story of the world. A sublime story it is, therefore. The life of men and nations has not been [125] a floundering on through useless disorder and confusion, trial and strife, war and bloodshed; but it has been a struggling onward to an end.
