I wanted to start this post so as not to hijack another, and because some seem genuinely confused as to why an IFB pastor, particularly, would hold to what to them, (and to me once, as well) comes close to perhaps heresy or a departure of the faith.
Let me first say that despite how strongly we hold to such a doctrine, one way or the other, it is not what we might consider a fundamental, or it shouldn't be IMHO, and so, I have never seen it as a separation issue, though I know of some who do. I won't judge them-its between them and the Lord.
I was not raised IFB-it is something I turned to in my 20's. However, saved in a C&MA church and raised in various churches in my youth, one things they all agreed on was a pre-tribulation rapture position. So, since my youth this is what I believed.
Shorlty after I was married to my wife, back in about 2005-ish, my wife began to seriously question me concerning the various positions on the timing of the catching away/rapture, whatever you want to call it. I explained to her all that I had ever been taught on the subject: The entire tribulation is the outpouring of God's wrath., so we won't go through it; it is for the Jews, the time of Jacob's trouble, so the church won't be there; Rev 4:1 seems to suggest the rapture as John sees a door open in heaven, (isn't Jesus called 'the door'?) and a voice that says "Come up hither", ( voice of the archangel?), so this must depict the rapture JUST before the tribulation is seen to begin; 1Thes 4 says, concerning the rapture, "Comfort one another with this', how can we find comfort in knowing we will go through great tribulation? And so on.
So, she began to lay out a pretty extensive argument both against the PreTR and for the PostT/PreWR Trib. To go into it all, I haven't time. But I told her that, to make her happy, and because I want to please God before man, OR her, I would take what we have both said, and prayerfully study it out for myself. I took about a year looking it over in scripture and praying over it before I was finally willing to say that I had to agree with her. I knew I was taking a stand considerably different than 99% of other IFB's and might lost friends and associates over it, but I believed, as I do now, that pleasing God was more important.
Some of what I found was, yes, Israel is the focus of the tribulation time. However, nowhere do we see that this must mean the church is not in existence. Jew have continued to live and thrive during the 'church age', and even with Israel being re-established as a nation, here we still are. The focus on them doesn't necessarily mean we can't be here any more-it is assumption, no more.
I have yet to hear anyone give a good explanation of what occurs in Rev 14:14. No, it isn't Jesus sitting on the church-we see Jesus in the clouds with a sickle, reaping His harvest. This takes place shortly after the seventh trumpet sounds, the last trumpet mentioned in scripture. We also see an angel shout to Him that the time has come. Last trumpet, Jesus in the clouds, voice of an angel from the temple, (an archangel?). sounds like about all that is needed to match what occurs in 1Thes 4 return of Christ. NO, we don't see those who sleep in Christ coming with Him, but that doesn't mean they aren't there-it is the ONLY specific example we are given of Jesus reaping His harvest, and it is followed immediately by the outpouring of God's wrath. Apparently the entire tribulation is NOT God's wrath, because we see a specific time the wrath falls.
I will continue when I have time. There's more! Please read, comment if you like, but again, this is not comprehensive, so no fights just yet.
