I would suggest, in this hypothetical scenario, that in fact you would not fall to your knees "this quick."
Luke 16:31
King James Version (KJV)
31And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
The Lord endorsed this truth by telling the story itself.
The resurrection of Chirst did not even persuade men.
The strong delusion brought upon those in the Tribulation period will deny the possibility for those that have in full knowledge not obeyed the Gospel to believe and repent, though not just one, but many...rose from the dead.
Where in scripture do we see that "everyone will know?"
It is not until His return at the end of the Tribulation that all will see him:
Revelation 1:7
King James Version (KJV)
7Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
This strengthens my belief in a pre-trib rapture, actually: at this point, the entire world, as we see here, will finally understand and confess that Jesus is Lord.
What need is there, and how could it be possible, that at this point the entire world is under strong delusion?
God bless.
