Before. Don’t presume to know all of God’s details. But there will be a NEW heaven and a NEW earth. Where he keeps Satan chained is His place to know. What Jerusalem is too.
You must admit (I pray) that there has to be a whole lot of reading between the lines to deduce he comes back secretly first and then 7 years later it’s unmistakable. There is NO scripture that supports an early rapture. Only erroneous interpretations.
Oh well, I was speaking as to the “man of sin” not necessarily to the “timing” of the rapture. Revelation speaks of Christ as having been that “child born of that woman” then caught up to heaven saved for the day where he will rule the nations with a rod of iron. Sounds to me like the beast system gets destroyed as well as those who carried his mark, then any survivors who remain are ruled by Christ during the 1000 year reign, while Satan remains chained. As to the timing of the “catching up of the saints” I’m somewhat flexible; but of the prophesied reality of the event I am in no doubt!
