That Day will come upon everyone the whole world over
Indeed! Those that remain on the earth and are not hidden from that time as per the Prophets, King David, and Paul at least. I follow the example of the Bereans in Acts. They relied on the OT to see if what Paul taught them was true. There are many, many passages in the OT that allude to a removal and protection of the righteous before all these things come upon the earth.
There is a definite allusion to something unique about those referred to as "on the earth" or "earth dwellers". it is a condemnation. The best example is Yeshua and the woman caught in the act of adultery. The religious leaders that brought her and tested Yeshua is in focus. Yeshua wrote in the earth, but John didn't say what it was. Well, there is quite a bit there.
It is the day after the feast of tabernacles as mentioned in John 7. This is a special day called Simchat Torah. The high priest would take "living water' from the pool of Siloam and offer it at the temple alter.
So now we can know what Yeshua wrote in the ground when these religious leaders confronted Yeshua about the adulterous woman. He wrote the names of those guys who confronted Him in the ground, these guys had forsaken the fount of living water, Yeshua, at the time of the "living water" being offered at the temple.
Jeremiah 17:13 O Lord, the hope of Israel,
All who forsake You shall be ashamed.
“Those who depart from Me
Shall be written in the earth,
Because they have forsaken the Lord,
The fountain of living waters.”
This goes back to who will go into the tribulation period. The scripture is replete that those who are the earth dwellers, on the earth, in the earth, etc will suffer that period. And throughout scripture, those that are called earth dwellers are those who are condemned. The Believers are never once referred to in scripture as earth dwellers.
King David, Isaiah, Jeremiah and many other locations give allusion to the righteous (both dead and living) being hidden and protected in the tabernacle of Yahweh during the calamities of the tribulation period. They didn't say "church" only because the mystery of the church had not been revealed to them.
And then it becomes an issue of what and who is the focus of the tribulation period. Scripture is clear about that also. And there is one unique and solitary condition that has to be met before Yeshua will return. And it has nothing to do with church, saints, etc. And the focus of the tribulation period is to bring about that event. Yeshua in Hosea said what it is and reiterated it in Matthew. Now go and study.
