“The ‘new covenant’ was established upon ‘better promises’—the promise of forgiveness of sins and of the grace of God to renew the heart and bring it into harmony with the principles of God’s law. ‘This shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts. . . . I will forgive their iniquity, and will remember their sin no more.’ Jeremiah 31:33, 34.
“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. . . .
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. The Saviour typified in the rites and ceremonies of the Jewish law is the very same that is revealed in the gospel. The clouds that enveloped His divine form have rolled back; the mists and shades have disappeared; and Jesus, the world's Redeemer, stands revealed. 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.’ ”
