Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.
[Patriarchs & Prophets pp 363>364] Adam and Eve, at their creation, had a knowledge of the law of God; they were acquainted with its claims upon them; its precepts were written upon their hearts. When man fell by transgression the law was not changed, but a remedial system was established to bring him back to obedience. The promise of a Savior was given, and sacrificial offerings pointing forward to the death of Christ as the great sin offering were established. But had the law of God never been transgressed, there would have been no death, and no need of a Savior; consequently there would have been no need of sacrifices.
Adam taught his descendants the law of God, and it was handed down from father to son through successive generations. But notwithstanding the gracious provision for man's redemption, there were few who accepted it and rendered obedience. By transgression the world became so vile that it was necessary to cleanse it by the Flood from its corruption. The law was preserved by Noah and his family, and Noah taught his descendants the Ten Commandments.
As men again departed from God, the Lord chose Abraham, of whom He declared, “Abraham obeyed My voice, and kept My charge, My commandments, My statutes, and My laws.” Genesis 26:5. To him was given the rite of circumcision, which was a sign that those who received it were devoted to the service of God—a pledge that they would remain separate from idolatry, and would obey the law of God. The failure of Abraham's descendants to keep this pledge, as shown in their disposition to form alliances with the heathen and adopt their practices, was the cause of their sojourn and bondage in Egypt.
Deuteronomy 7:3 Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son. 4 For they will turn away thy son from following me, that they may serve other gods: so will the anger of the Lord be kindled against you, and destroy thee suddenly.
May God add His blessing to the study of His word. “Good night” and God bless!
