Adam taught his descendants the law of God, which law was handed down to the faithful through successive generations. The continual transgression of God’s law called for a flood of waters upon the earth. The law was preserved by Noah and his family, who for right-doing were saved in the ark by a miracle of God. Noah taught his descendants the Ten Commandments. The Lord preserved a people for Himself from Adam down, in whose hearts was His law. He says of Abraham, He “obeyed My voice, and kept My charge, My commandments, My statutes, and My laws.” Genesis 26:5. (SR 146.1) MC VC

“I am the Almighty God; walk before Me, and be thou perfect. And I will make My covenant between Me and thee, and will multiply thee exceedingly.” Genesis 17:1, 2. “And I will establish My covenant between Me and thee and thy seed after thee in their generations, for an everlasting covenant, to be a God unto thee, and to thy seed after thee.” Genesis 17:7. (SR 146.3) MC VC

He then required of Abraham and his seed, circumcision, which was a circle cut in the flesh, as a token that God had cut them out and separated them from all nations as His peculiar treasure. By this sign they solemnly pledged themselves that they would not intermarry with other nations, for by so doing they would lose their reverence for God and His holy law, and would become like the idolatrous nations around them.
