It was my honor to place before Mr. Lincoln arguments designed to prove the divine authority and inspiration of the Scriptures, accompanied by the arguments of infidel objectors in their own language. To the arguments on both sides Mr. Lincoln gave a most patient, impartial, and searching investigation. To use his own language, he examined the arguments as a lawyer who is anxious to reach the truth investigates testimony. The result was the announcement by himself that the argument in favor of the divine authority and inspiration of the Scriptures was unanswerable. I could say much more on this subject, but as you are the person addressed, for the present I decline. The assassin Booth, by his diabolical act, unwittingly sent the illustrious martyr to glory, honor, and immortality; but his false friend has attempted to send him down to posterity with infamy branded on his forehead, as a man who, notwithstanding all he suffered for his country's good, was destitute of those feelings and affections without which there can be no real excellency of character. Sir, I am with due respect your obedient servant, JAS. SMITH. N.B.--It will no doubt be gratifying to the friends of Christianity to learn that very shortly after Mr. Lincoln became a member of my congregation, at my request, in the presence of a large assembly at the annual meeting of the Bible Society of Springfield, he delivered an address the object of which was to inculcate the importance of having the Bible placed in possession of every family in the State. In the course of it he drew a striking contrast between the Decalogue and the moral codes of the most eminent lawgivers of antiquity, and closed (as near as I can recollect) in the following language: "It seems to me that nothing short of infinite wisdom could by any possibility have devised and given to man this excellent and perfect moral code. It is suited to men in all conditions of life and includes all the duties they owe to their Creator, to themselves, and to their fellow-men." J. S.
