Thanks Dave, I agree very much with your point from Mt 24:40-41 and have always thought it to be relevant in showing that not all who are left behind at the rapture have the mark, else they would not be side by side with believers at the time of the Lord’s post-tribulational return, as you correctly point out. In my view, this shows that not all who have fled the Antichrist have passed through the straight gate of regeneration. This explains why some are left behind at the rapture but not destroyed with those who have passed into irreversible reprobration by taking the mark. Many of these gentile survivors, greatly humbled by the recent supernatural happenings, will count it a supreme privilege to assist in the return of the Jews to their land. The mystery of God will be finished (Rev 10:7), and those that are left from among the nations (Isa 24:6) are awakening to the meaning of what has transpired (Eze 39:23, 27; Rev 10:7).

“It is this clearly revealed activity of gentiles who have manifestly survived the tribulation that leads me to conclude, on the basis of 1Cor 15:23, 52 and 1Thes 4:14, that not all the unsaved of the earth take the mark of the beast, else they would not have survived Christ’s return.”

I believe this can be further demonstrated by Matthew 24:40-41. Two men will be in the field, one taken and the other left. This clearly shows that the non-believer and believer will be working side by side during the tribulation and right up until the second coming of Yeshua.

I believe these group of non-believers that do not have the mark would best fit militia and anti-government groups that will not take the mark strictly out of rebellion against “Big Brother.” These militia camps would also provide safe haven for Christians who share a common distaste for the system of the Anti-Christ.

I believe this scripture clearly shows non-believers without the mark at the return of Christ. If they had the mark, a believer could not safely be working beside them, as this scripture clearly implies.
