Amen! I think we will witness both according to the Word, (should the Lord tarry) a revival AND a falling away simultaneously. And that door to the Ark is about to close. Come up hither.
Although we're seeing previews of what's coming, I think the great falling away will happen immediately following the rapture which will include the departure of the Holy Spirit, "that which restrains" (2 Thess 2:7).
Revelation 6:1-8 will happen so quickly that before you know it, 1/4 of the world is dead (v.8).
Glad we won't be there but instead celebrating the seven-year Marriage Supper of the Lamb. A seven-year party. Never been to one of those. Looking forward to it.
