I send forth the volume now in the reader's hands, with much diffidence, and a very deep sense of responsibility. It is a peculiarly serious undertaking to attempt a Commentary on the Gospel of St. John.

This "Commentary" is so extensive that it occupies far more space than the "Expository Thoughts," and is, I must honestly confess, the principal part of the work. To some it may appear far too long and full. But the circumstances of the times are mu justification. We live in a day of abounding vagueness and indistinctness on doctrinal subjects in religion. Now, if ever, it is the duty of all advocates of clear, well-defined, sharply-cut theology, to supply proof that their views are thoroughly borne out by Scripture. I have endeavoured to do so in this Commentary. I hold that the Gospel of St. John, rightly interpreted, is the best and simplest answer to those who profess to admire a vague and indistinct Christianity. (From the Preface
