Had ye believed Moses, ye would have believed me: for he wrote of me. John 5:46. LHU 306.1
The Word of God includes the Scriptures of the Old Testament as well as of the New. One is not complete without the other. Christ declared that the truths of the Old Testament are as valuable as those of the New. Christ was as much man's Redeemer in the beginning of the world as He is today. Before He clothed His divinity with humanity and came to our world, the gospel message was given by Adam, Seth, Enoch, Methuselah, and Noah. Abraham in Canaan and Lot in Sodom bore the message, and from generation to generation faithful messengers proclaimed the Coming One.... LHU 306.2
Of Christ's life and death and intercession, which prophets had foretold, the apostles were to go forth as witnesses. Christ in His humiliation, in His purity and holiness, in His matchless love, was to be their theme. And in order to preach the gospel in its fullness, they must present the Saviour not only as revealed in His life and teachings, but as foretold by the prophets of the Old Testament and as symbolized by the sacrificial service.... LHU 306.3
In every age there is a new development of truth, a message of God to the people of that generation. The old truths are all essential; new truth is not independent of the old, but an unfolding of it. It is only as the old truths are understood that we can comprehend the new. When Christ desired to open to His disciples the truth of His resurrection, He began “at Moses and all the prophets,” and “expounded unto them in all the scriptures the things concerning himself” (Luke 24:27). But it is the light which shines in the fresh unfolding of truth that glorifies the old. He who rejects or neglects the new does not really possess the old. For him it loses its vital power and becomes but a lifeless form. LHU 306.4
There are those who profess to believe and to teach the truths of the Old Testament, while they reject the New. But in refusing to receive the teachings of Christ, they show that they do not believe that which patriarchs and prophets have spoken.... LHU 306.5
In rejecting the Old, they virtually reject the New; for both are parts of an inseparable whole. No man can rightly present the law of God without the gospel, or the gospel without the law. The law is the gospel embodied, and the gospel is the law unfolded. The law is the root, the gospel is the fragrant blossom and fruit which it bears. LHU 306.6
The Old Testament sheds light upon the New, and the New upon the Old. Each is a revelation of the glory of God in Christ. Both present truths that will continually reveal new depths of meaning to the earnest seeker (Christ's Object Lessons, 126-128). LHU 306.7
