“The same law that was engraved upon the tables of stone is written by the Holy Spirit upon the tables of the heart. Instead of going about to establish our own righteousness, we accept the righteousness of Christ. His blood atones for our sins. His obedience is accepted for us. Then the heart renewed by the Holy Spirit will bring forth ‘the fruits of the Spirit.’ Through the grace of Christ we shall live in obedience to the law of God written upon our hearts. Having the Spirit of Christ, we shall walk even as He walked. Through the prophet He declared of Himself, ‘I delight to do Thy will, O My God: yea, Thy law is within My heart.’ Psalm 40:8. And when among men He said, ‘The Father hath not left Me alone; for I do always those things that please Him.’ John 8:29.
“The apostle Paul clearly presents the relation between faith and the law under the new covenant. He says: ‘Being justified by faith, we have peace with God through our Lord Jesus Christ.’ ‘Do we then make void the law through faith? God forbid: yea, we establish the law.’ ‘For what the law could not do, in that it was weak through the flesh’—it could not justify man, because in his sinful nature he could not keep the law—'God sending His own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: that the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.’ Romans 5:1; 3:31; 8:3, 4.
“God’s work is the same in all time, although there are different degrees of development and different manifestations of His power, to meet the wants of men in the different ages. Beginning with the first gospel promise, and coming down through the patriarchal and Jewish ages, and even to the present time, there has been a gradual unfolding of the purposes of God in the plan of redemption. . . . He who proclaimed the law from Sinai, and delivered to Moses the precepts of the ritual law, is the same that spoke the Sermon on the Mount. The great principles of love to God, which He set forth as the foundation of the law and the prophets, are only a reiteration of what He had spoken through Moses to the Hebrew people: ‘Hear, O Israel: The Lord our God is one Lord: and thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.’ Deuteronomy 6:4, 5. ‘Thou shalt love thy neighbor as thyself.’ Leviticus 19:18. The teacher is the same in both dispensations. God’s claims are the same. The principles of His government are the same. For all proceed from Him ‘with whom is no variableness, neither shadow of turning.’ James 1:17” (Ellen G. White, Patriarchs and Prophets, 372, 373).
