It is true, they had some judicious, weighty, moral, sayings; for in this argument, I would allow them as much as can be allowed them, consistently with fact. But no system of heathen morals proposed any thing, as motives drawn from another world of any force to induce people to act with any due reverence to it--or to prepare for a happy immortality. Reason, consequently, doth not, properly speaking, look into another world. It merely conjectures about it.--The Gospel, or a divine revelation only fully discloses an Eternity to man.--It lays before him Immortality: an Immortality of blessedness, when life is no more, if it have been improved in a pious and virtuous manner.--It denounces on the wicked everlasting misery. _But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the Gospel._-----We can now look through all the wastes and glooms of death and the grave to a resurrection of the body--to a judgment-seat--to an endless existence after death--to eternal rewards for the pious--and everlasting woe to the despisers of God and Virtue. By the Gospel, therefore, we have hope, pleasing enrapturing hope--we have light, like the glorious luminary of the sky in his meridian altitude--we have life, spiritual and divine--we have the saving knowledge of God--we have a fulness of felicity opened before us, and promised to us, upon our repentance, faith, and new obedience. 5. Reason and conscience are unable to renew and change our hard hearts, or to give us a true and real light of the excellency of spiritual and divine things. To subdue the obduracy of the heart, to slay the enmity there is in us against the law, character, and perfections of God, is beyond all that reason and conscience can effect. The powers of reason can tell us of our dark, blinded corrupt state. Men of science and liberal enquiry, in all ages, and among all people, have seen, confessed, and bewailed the imperfections and frailties, the infirmities and exceeding depravation of human nature; like a magnificent pile of buildings in ruin--or a fertile and luxuriant soil overrun with noxious plants. It was impossible for candid and inquisitive men among heathen tribes not to have discovered the perverseness and vices of human nature, in general, they are so plain; though they called some things Virtues which were not--and some things Vices which were not. But reason never could suggest, or give a hint of any plan of restoration to a right temper or a holy and innocent condition. There is nothing--no principle in man--no light--or quality that can sanctify, purify, and regenerate the soul. But an inward renovation is absolutely necessary to moral happiness, to become like God, to be either conformed to his perfections, or fitted to enjoy his presence in heaven. The wisest and best heathen confessed it was not in man to heal the moral
