We are in the Tribulation even as we write. Therefore it applies to us right now.
There is tribulation, and then there is great tribulation, after the translation of the church.
We are in the former, pretty much always, somewhere in the world, but we are not in the latter. Not yet.
When that happens, it will be hell on earth, for hell will be ruling earth. If you're here then, you will see the difference clearly.
