Jesus showed the importance of the Old Testament as a witness to His mission. Many professed Christians now discard the Old Testament, claiming that it is no longer of any use. But such is not Christ’s teaching. So highly did He value it that at one time He said, “If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.” Luke 16:31.
It is the voice of Christ that speaks through patriarchs and prophets, from the days of Adam even to the closing scenes of time. The Saviour is revealed in the Old Testament as clearly as in the New. It is the light from the prophetic past that brings out the life of Christ and the teachings of the New Testament with clearness and beauty. The miracles of Christ are a proof of His divinity; but a stronger proof that He is the world’s Redeemer is found in comparing the prophecies of the Old Testament with the history of the New.
