In the Lord's Day by Arlen L Chitwood and published by Classics.
This book, IN THE LORD’S DAY, deals with:
1) The time of the resurrection of the dead and translation of the living “in Christ” (commonly called “the rapture”).
2) Judgment awaiting Christians at Christ’s judgment seat following their removal from the earth.
3) Events related to this judgment, which precede and anticipate the coming Messianic Era.
These are the things dealt with in the opening four chapters of the Book of Revelation. And viewing the book as a whole, these opening four chapters provide a sequence of events as they pertain to the rapture and judgment seat which must occur at the conclusion of the present dispensation but before the beginning of the seven-year Tribulation period on earth.
The Book of Revelation is the only book in Scripture which provides a comprehensive, continuous coverage of this nature. The same truths concerning these events are taught elsewhere in Scripture, particularly in Old Testament typology. But the Book of Revelation is the only book in Scripture where these events are all seen together in a sequence which includes the subsequent Tribulation. A separation of Christians on the basis of faithfulness will occur, but not at the time of the rapture. Rather, this separation will occur at the judgment seat alone.
