29. And Cain said unto the Lord, Satan tempted me because of my brother's flocks. And I was angry: for his offering you accepted and mine was not: My punishment is greater than I can bear. Behold you have driven me out this day from the face of men, and from your face shall I be hid also; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass that he that findeth me will slay me because of mine iniquities, for these things are not hid from the Lord. And the Lord said unto him, Therefore, whoever slays Cain, vengeance shall be taken on him seven fold. And the Lord set a mark upon Cain, lest any finding him should kill him. 30. The object of the foregoing quotations is to show to this class the way by which mankind were first made acquainted with the existence of a God: that it was by a manifestation of God to man, and that God continued, after man's transgression to manifest himself to him and to his posterity; and, notwithstanding they were separated from his immediate presence, that they could not see his face, they continued to hear his voice. 31. Adam thus being made acquainted with God, communicated the knowledge which he had unto his posterity; and it was through this means that the thought was first suggested to their minds that there was a God. Which laid the foundation for the exercise of their faith, through which they could obtain a knowledge of his character and also of his glory. 32. Not only was there a manifestation made unto Adam of the existence of a God, but Moses informs us, as before quoted, that God condescended to talk with Cain after his great transgression, in slaying his brother, and that Cain knew that it was the Lord that was talking with him: so that when he was driven out from the presence of his brethren, he carried with him the knowledge of the existence of a God; and, through this means, doubtless, his posterity became acquainted with the fact that such a being existed. 33. From this we can see that the whole human family, in the early age of their existence, in all their different branches, had this knowledge disseminated among them; so that the existence of God became an object of faith, in the early age of the world. And the evidences which these men had of the existence of a God, was the testimony of their fathers in the first instance. 34. The reason why we have been thus particular on this part of our subject, is that this class may see by what means it was that God became an object of faith among men after the fall; and what it was that stirred up the faith of multitudes to feel after him; to search after a knowledge of his character, perfections and attributes, until they became extensively acquainted with him; and not only commune with him, and behold his glory, but be partakers of his power and stand in his presence.
