The contents of this book were first given out by the author at Bible Conferences, and then appeared in their present form in Studies in the Scriptures. As the subject of them is of such importance to students of prophecy, and as so little has been published thereon, we have deemed it advisable to issue them, complete, in book form. So far as the writer is aware, only two or three comparatively brief booklets and essays have appeared on this particular theme, though to their contents we are indebted for a number of helpful suggestions. Our aim has been to present as comprehensive an outline as our space would allow. Much of what we have advanced will no doubt be new to the great majority of our readers. Frequently we have been obliged to deviate from the interpretations of those who have gone before us. Nevertheless, we have sought to give clear proof texts for everything advanced, and we would respectfully urge the reader to examine them diligently and impartially. The subject is unspeakably solemn, and before each chapter was commenced we lifted up our heart to God that we might write with His fear upon us. To speculate about any of the truths of Holy Writ is the height of irreverence: better far to humbly acknowledge our ignorance when God has not made known His mind to us. Only in His light do we see light. Secret things belong unto the Lord, but the things which are revealed (in Scripture) belong unto us and to our children. Therefore, it is our bounden duty, as well as holy privilege, to search carefully and prayerfully into what God has been pleased to tell us upon this, as upon all other subjects of inspiration. Fully conscious are we that we have in no wise exhausted the subject. As the time of the manifestation of the Man of Sin draws near, God may be pleased to vouchsafe a fuller and better understanding of those parts of His Word which make known "the things which must shortly come to pass." That others may be led to make a more thorough inquiry for themselves is our earnest hope, and that God may be pleased to use this work to stimulate to this end is our prayer. May He deign to use to His glory whatever in this book is in harmony with His Word, and cause to fall to the ground whatever in it is displeasing to Him. Arthur W. Pink
