The Word of God includes the Scriptures of the Old Testament as well as of the New. One is not complete without the other.
The Old Testament, no less than the New, should receive attention. As we study the Old Testament, we shall find living springs bubbling up where the careless reader discerns only a desert.
There is no discord between the Old Testament and the New. In the Old Testament we find the gospel of a coming Saviour; in the New Testament we have the gospel of a Saviour revealed as the prophecies had foretold. While the Old Testament is constantly pointing forward to the true offering, the New Testament shows that the Saviour prefigured by the typical offerings has come. The dim glory of the Jewish age has been succeeded by the brighter, clearer glory of the Christian age.
Christ as manifested to the patriarchs, as symbolized in the sacrificial service, as portrayed in the law, and as revealed by the prophets, is the riches of the Old Testament. Christ in His life, His death, and His resurrection, Christ as He is manifested by the Holy Spirit, is the treasure of the New Testament. Our Saviour, the outshining of the Father’s glory, is both the Old and the New.... 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.
Jesus said of the Old Testament Scriptures—and how much more it is true of the New—“They are they which testify of me” (John 5:39).... Yes, the whole Bible tells of Christ. From the first record of creation, for “without him was not any thing made that was made” (John 1:3), to the closing promise, “Behold, I come quickly” (Revelation 22:12), we are reading of His works and listening to His voice. If you would become acquainted with the Saviour, study the Holy Scriptures. FLB 12
There is need of prayer—earnest, prevailing prayer. Pr 116
