THESE SCRIPTURES TELL US WHAT HAPPENS JUST BEFORE THE RAPTURE
"Blood and fire and vapor of smoke.....BEFORE THE COMING of the great and awesome Day of the Lord."
"For wherever the carcass is, THERE (in Israel) the eagles will be gathered together. Immediately AFTER THE TRIBULATION of those days.."
The "blood and fire and vapor of smoke" is God's Gog-Magog War of great tribulation in Israel that produces the dead "carcass"es on which "the eagles will be gathered together" to feed "Immediately AFTER THE TRIBULATION", and "BEFORE THE COMING of the great and awesome Day of the Lord".
God's great tribulation of Israel is our sign to watch for our pending rapture according to:
Luke 21:28 &30
"Now when these things BEGIN TO HAPPEN, look up and lift up your heads because your redemption draws near. So you also, when you see THESE THINGS HAPPENING , know that the kingdom of God is near."
