I believe it happens before Revelation 7, yes.
Keep in mind, I’ve shifted my position on this a LOT since I first started studying it in 1981.
Probably the biggest shift is that I’ve gone from KNOWING my position is right, to seeing it as something no man can know. Fortunately, I see it not as my primary belief, but as a backdrop to it - A sort of background noise.
I was talking to a music director at a large church in Louisville a while back. It was a church where many members were also teachers and professors at a local Christian university. The subject was about all the pastors in the small churches where I now live being so absolutely sure of doctrine that I don’t believe they can support, nor do they try to.
His comment was that you don’t see a lot of that at his church. He said he’s found that, regarding “controversial” Christian issues, the more a person knows about the word of God, the less sure they are of their position. Not in every case, of course, but generally speaking.
I had to finally end it with a member here that was spouting his opinion as though his was the word of God and mine wasn’t, even though both of us were getting our opinions from His word, and I can only assume, prayerfully so.
I no longer suffer such arguments for long.
Matt 24:39-41 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be. Then shall two be in the field; the one shall be taken, and the other left. Two women shall be grinding at the mill; the one shall be taken, and the other left.It appears that there will be a separation when Christ returns. Like in the days of Noah, some will be taken away to judgment and those left behind will enter the millennial kingdom without dying. This is the preservation of the flesh Matthew 24:22. I think Schofield got it right, this is not the rapture, this is the second coming when Christ will rule with rod of iron.
