Let us beware of undervaluing, or despising the Old Testament. In its place and proportion, the Old Testament is just as valuable as the New. There are probably many rich passages in that part of the Bible which have never yet been fully explored. There are deep things about Jesus in it, which many walk over like hidden gold mines, and know not the treasures beneath their feet. Let us reverence all the Bible. All is given by inspiration, and all is profitable. One part throws light upon another, and no part can ever be neglected without loss and damage to our souls.
