A couple of weeks ago we pointed out that we should not expect to find the church on earth during the great tribulation, and especially not to find the church in Jerusalem when the Lord judges the armies of the northerner and drives him from Palestine. Joel’s prophecy has almost nothing to say about godly Gentiles, dead, alive or in resurrection bodies. Reading us into earlier portions of the book is highly questionable.
That changes with today’s reading. It’s subtle, but I think we are definitely there, though even the most careful students of Joel would not have been able to easily identify us prior to the writing of Revelation near the end of the first century.
