In this volume the sole aim of the writer has been to trace the unity of thought in one of the greatest and most difficult books of the New Testament. He has endeavoured to picture his reader as a member of what is known in the Sunday-schools of Wales as “the teachers’ class,” a thoughtful Christian layman, who has no Greek, and desires only to be assisted in his efforts to come at the real bearing and force of words and to understand the connection of the sacred author’s ideas. It may not be unnecessary to add that this design by no means implies less labour or thought on the part of the writer. But it does imply that the labour is veiled. Criticism is rigidly excluded.
