There is a reason why the Lord did not come for us as we previously expected this past spring. We now know that the 70th Week is the Sabbatical cycle of Rosh 2008 to Rosh 2015. The Lord must return at the end of the 6th year of the Sabbatical cycle to save Israel (Jacob) out of the time of trouble to then enter into His rest typified by the Sabbath year (the 7th year in the Sabbatical cycle). The Sabbath year of rest (Christ brings rest to Israel and the world with His coming) begins on Rosh 2014 and runs to Rosh 2015, which is the completion of the 70th Week. The way one recognizes the 70th Week is by its connection to the time of Jacob's Trouble and the beginning of the Lord's Day.
To see the reasons why the Sabbatical cycle of Rosh 2008 to Rosh 2015 is the 70th Week of Daniel and how the Lord shortens the time of great tribulation, please see the 2 new articles at www.godstimeline.net under the section "Charts and Commentaries".
The two new articles are entitled "A Correction Regarding the 70th Week and the Time of Jacob's Trouble" and "The Shortening of the Days".
I hope these articles will show you the scriptural reasons why the Lord should return for His own (the resurrection/rapture) in the Spring of 2012.
