Many people who call themselves Christians today know or have heard the term the Great Tribulation that will come upon this earth; and many believe that this tribulation era will last 3.5 or seven years, but is it true!
They believe that: the LAST Prophecies explore the biblical prophecies listed below that will happen within the first 3 years of the dreaded Seven, Year Tribulation Period.
In Christian eschatology, the post-tribulation rapture doctrine is the belief in a combined resurrection and gathering of the saints coming after the Great Tribulation period.
Pre tribulation is the rapture concept, and refers to the eschatological event of both dead and living believers being caught up together in a moment to meet in the air the Lord!
But the problem is, the bible does not teach these concepts; although it does teach that the time will come when the Lord will come back to this earth and will rescue his elect!
Those verses are found in I Thessalonians 4:13-17.
