And then, if you turn to the whole Book, the same thing is true, though in a modified sense there. I have no time to dwell upon that fruitful field, but the silence of Scripture is quite as eloquent as its speech. Think, for instance, of how many things in the Bible are taken for granted which one would not expect to be taken for granted in a book of religious instruction. It takes for granted the being of a God. It takes for granted our relations to Him. It takes for granted our moral nature. In its later portions, at all events, it takes for granted the future life. Look at how the Bible, as a whole, passes by, without one word of explanation or alleviation, a great many of the difficulties which gather round some of its teaching. For instance, we find no attempt to explain the divine nature of our Lord; or the existence of the three Persons in the Godhead. It has not a word to say in explanation of the mystery of prayer; or of the difficulty of reconciling the Omnipotent will of God on the one hand, with our own free will on the other. It has not a word to explain, though many a word to proclaim and enforce, the fact of Christ's death as the atonement for the sins of the whole world. Observe, too, how scanty the information on points on which the heart craves for more light. How closely, for instance, the veil is kept over the future life! How many questions which are not prompted by mere curiosity, our sorrow and our love ask in vain! Nor is the incompleteness of Scripture as a historical book less marked. Nations and men appear on its pages abruptly, rending the curtain of oblivion, and striding to the front of the stage for a moment, and then they disappear, swallowed up of night. It has no care to tell the stories of any of its heroes, except for so long as they were the organs of that divine breath, which, breathed through the weakest reed, makes music. The self-revelation of God, not the acts and fortunes of even His noblest servants, is the theme of the Book. It is full of gaps about matters that any sciolist or philosopher or theologian would have filled up for it. There it stands, a Book unique in the world's history, unique in what it says, and no less unique in what it does not say. 'Many other things truly did' that divine Spirit in His march through the ages, 'which are not written in this book; but these are written that ye might believe.' II. And so that brings me next to say a word or two about the more immediate purpose which explains all these gaps and incompletenesses. John's Gospel, and the other three Gospels, and the whole Bible, New Testament and Old, have this for their purpose, to produce in men's hearts the faith in Jesus as 'the Christ' and as 'the Son of God.'
