The great interest we feel in Abraham is as "the father of the faithful," as a model of that exalted sentiment which is best defined and interpreted by his own trials and experiences; and hence I shall not dwell on the well known incidents of his life outside the varied calls and promises by which he became the most favored man in human annals. It was his faith which made him immortal, and with which his name is forever associated. It is his religious faith looming up, after four thousand years, for our admiration and veneration which is the true subject of our meditation. This, I think, is distinct from our ordinary conception of faith, such as a belief in the operation of natural laws, in the return of the seasons, in the rewards of virtue, in the assurance of prosperity with due regard to the conditions of success. Faith in a friend, in a nation's future, in the triumphs of a good cause, in our own energies and resources _is_, I grant, necessarily connected with reason, with wide observation and experience, with induction, with laws of nature and of mind. But religious faith is supreme trust in an unseen God and supreme obedience to his commands, without any other exercise of reason than the intuitive conviction that what he orders is right because he orders it, whether we can fathom his wisdom or not. "Canst thou by searching find out Him?" Yet notwithstanding the exalted faith of Abraham, by which all religious faith is tested, an eternal pattern and example for our reverence and imitation, the grand old man deceived both Pharaoh and Abimelech, and if he did not tell positive lies, he uttered only half truths, for Sarah was a half sister; and thus he put expediency and policy above moral rectitude,--to be palliated indeed in his case by the desire to preserve his wife from pollution. Yet this is the only blot on his otherwise reproachless character, marked by so many noble traits that he may be regarded as almost perfect. His righteousness was as memorable as his faith, living in the fear of God. How noble was his disinterestedness in giving to Lot the choice of lands for his family and his flocks and his cattle! How brave was he in rescuing his kinsman from the hands of conquering kings! How lofty in refusing any remuneration for his services! How fervent were his intercessions with the Almighty for the preservation of the cities of the plain! How hospitable his mode of life, as when he entertained angels unawares! How kind he was to Hagar when she had incurred the jealousy of Sarah! How serene and dignified and generous he was, the model of courtesy and kindness!
