Here, then, is a fearful contradiction between the religion of conscience and the religion of the understanding; the one pronouncing evil to be the antagonist, the other to be the agent, of the Divine will. In every age has this difficulty laid a heavy weight upon the human heart; in every age has it pointed the sarcasm of the blasphemer, mingled an occasional sadness with the hopes of benevolence, and tinged the devotion of the thoughtful with a somewhat melancholy trust. The whole history of speculative religion is one prolonged effort of the human mind to destroy this contrariety; system after system has been born in the struggle to cast the oppression off,--with what result, it will be my object at present to explain. The question which we have to consider is this, "How should a Christian think of the origin and existence of evil?" I propose to advert, first, to the speculative; secondly, to the scriptural; thirdly, to the moral relations of the subject; to inquire what relief we can obtain from philosophical schemes, from biblical doctrine, and from practical Christianity. * * * * * Let us then, for final decision, consult the practical spirit of Christianity, and ascertain to what view of the origin of sin it awards the preference. Is it well for the consciences and characters of men, to consider God--either directly or through his dependant, Satan, either by his general laws or by vitiating the constitution of our first parents--as the primary source of moral evil? _or_, on the contrary, to regard it as in no sense whatever willed by the Supreme Mind, and absolutely inimical to his Providence? Are we most in harmony with the characteristic spirit of the Gospel when we call sin his instrument, or when we call it his enemy? For myself, I can never sit at the feet of Jesus, and yield up a reverential heart to his great lessons, without casting myself on the persuasion, that God and evil are everlasting foes; that never, and for no end, did he create it; that his will is utterly against it, nor ever touches it, but with annihilating force. Any other view appears to be injurious to the characteristic sentiments, and at variance with the distinguishing genius, of Christian morality.
