The rapture ... for some people is a matter of much debate; there are different views, arguments and more arguments.
For many people, it doesn’t matter to them when it will be, while others insist on their position or view.
Of course, it could be a secondary issue, but it is not.
The rapture of the church is for the church, not for others.
It is the church’s “blessed hope” and the church's great historic event.
Why is it important?
The rapture is important because it is in the Bible, so we need to look for it throughout all the scriptures to properly understand it.
Anyone who does not understand the snatching up of the saints to meet the Lord in the clouds (the rapture), it can be said, that the whole subject gets blury.
I do not intend to expand the theological dispute or decide this is the right way , but a few key important things need to be cleared out, that will help you understand this great future event.
Therefore it is like almost all other Bible study, for understanding we need to go back to the beginning.
