i am no guru on this cos i have nvr been to bible school so
wadever knowledge i have is based on wad i understand from the
christians i noe from different denominations and some pastors as
well...
basically, all christians believe there will be a 7-year period
of tribulation that earth will witness but of cuz no man noes the
hour it will start...the differences begins in the issue of the
rapture of the believers, when it will happen...
1) pre-tribulation teaches that christians are spared from the
tribulation...they will rapture before tribulation
begins...christians who hold this belief usually believe in
predestination(once saved, always saved)...
2) mid-tribulation teaches that christians have to go thru
tribulation but only for 3.5 out of the 7 years...i dun really noe
where the biblical references are but thats wad i understand from
this teaching...
3) post-tribulation teaches that christians have to go thru the
full 7 years of tribulation...this is to test their faith if they
can hold out thru the tribulation...christians holding this belief
usually believe tat salvation is by freewill and tat it can be
lost...hence the tribulation is one of the tests of their faith to
see if its wavering...
4) partial tribulation is slightly different from the rest as it
teaches tat there are 2 raptures instead of 1...the 1st rapture
happens before tribulation and some christians(chosen by God) will
be raptured...then after the 7 years of tribulation, a 2nd batch of
christians will be raptured after getting their faith tested...
i hope i have given a reasonable enuff reply...:)
Just to add on, the last view is promoted by Van Kampen but
it never really became popularly accepted. So it really boils down
to the three main views.
