Reba,
I'm aware that Jesus mentions "great tribulation".  The question is, how do people come up with the conclusion that it is seven years long?  The only time period associated with great tribulation is a 10 day period mentioned in Rev. 2:10.  That is the same time period between the ascencion of Jesus and Pentecost.

I asked this question in the apologetics page and have not received a solid answer.  What is the Biblical basis for the seven year tribulation?  This tract above is all theoretical if the basis for the tribulation is not established.

JudgeNot,
With all due respect, your references do now show the basis for the 7 year tribulation.  They only show what you think will happen during that time (and following) based on the presupposition that the 7 year tribulation is true.

2nd Timothy,
One does not to need to know that much Hebrew to know that a week is seven years in the Bible compared to 7 days today.  They can simply read the account of the life of Jacob in his acquiring of Rachel and Leah.

In order for the 70th week of Daniel's prophecy to be the tribulation, one must know when the decree to restore and rebuild Jerusalem began or the whole idea falls apart.

Sincerely,

What is the Biblical basis for the seven year tribulation period?  Where is the seven year tribulation in the Bible?
