It was their own evil heart of unbelief, controlled by Satan, that led them to hide their light, instead of shedding it upon surrounding peoples; it was that same bigoted spirit that caused them either to follow the iniquitous practices of the heathen or to shut themselves away in proud exclusiveness, as if God’s love and care were over them alone.

As the Bible presents two laws, one changeless and eternal, the other provisional and temporary, so there are two covenants. The covenant of grace was first made with man in Eden, when after the Fall there was given a divine promise that the seed of the woman should bruise the serpent’s head. To all men this covenant offered pardon and the assisting grace of God for future obedience through faith in Christ. It also promised them eternal life on condition of fidelity to God’s law. Thus the patriarchs received the hope of salvation. (PP 370.2) MC VC

This same covenant was renewed to Abraham in the promise, “In thy seed shall all the nations of the earth be blessed.” Genesis 22:18. This promise pointed to Christ. So Abraham understood it (see Galatians 3:8, 16), and he trusted in Christ for the forgiveness of sins. It was this faith that was accounted unto him for righteousness. The covenant with Abraham also maintained the authority of God’s law. The Lord appeared unto Abraham, and said, “I am the Almighty God; walk before Me, and be thou perfect.” Genesis 17:1. The testimony of God concerning His faithful servant was, “Abraham obeyed My voice, and kept My charge, My commandments, My statutes, and My laws.” Genesis 26:5. And the Lord declared to him, “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.

Though this covenant was made with Adam and renewed to Abraham, it could not be ratified until the death of Christ. It had existed by the promise of God since the first intimation of redemption had been given; it had been accepted by faith; yet when ratified by Christ, it is called a new covenant. The law of God was the basis of this covenant, which was simply an arrangement for bringing men again into harmony with the divine will, placing them where they could obey God’s law. (PP 370.4) MC VC
