Bible teacher Mr. Harold Camping's "Time Has An End."
Most of the spiritual nature of his studies in this book are still accurate.
There are few corrections required such as the nature of "judgment day," being spiritual rather than physical and annihilation of unsaved rather than having a place called "hell" for the unsaved to be tormented forevermore.
The timeline of Biblical history and many truths reveled through progressive revelation are still very accurate and faithful in the Bible study.
The rapture of God's elect will occur on the last day of judgment day, which possibly may happen on the 1600th day of judgment which began on May 21, 2011 and will end on Oct 7, 2015, the last day of the Feast of Tabernacle. This is our hope and great expectation to be with Lord Jesus Christ forever.
