Actually, still being on this earth at that time would not be a blessing nor a good testimony. Those who are left behind will be, at that time, unbelievers. To be counted among them in that moment is not at all something we should desire. Ministry in the tribulation will be more than sufficient, even with an angel flying through the heavens declaring the gospel message of the Blood of Christ.
Additionally, if any one person was left here on earth who was saved to the uttermost under the Gospel of Grace by way of the seal of Holy Spirit as the body of Christ right now, if any one of them took the mark or worshipped the beast's image or wondered after him, that would create a horrid discontinuity and contradiction within God's own word and ways. None of us, therefore CAN be left here who are saved by grace, especially given that the Lord knows all the future and therefore never surprised by any of it. The dichotomy would bring about a measure of contradiction within God Himself, and that simply cannot be.
This, then, gives to us reasoning behind the loss of salvation belief to which some adhere. For the pre-wrath gang to hold to their beliefs, they must believe in the loss of salvation under the Gospel of Grace contrary to the words of Paul. That they don't see all the tribulation as being the wrath of God, that's remarkable in itself given that a fourth of the world's population will perish in just the first half with another fourth perishing in the second half, thus half the original population of the world left after all is said and done at the Second Coming.
