I would not blaspheme if I were you. Attempts at making fun of the LORD usually ends up with one having egg, or worse, on ones face. IF everyone thinks Christ is returning on the 23d, then He is not returning on that date. The Scriptures do not give us the date. Christ said no man knows the date, thus the 23d cannot be the date. He will return when He returns. We simply look up for our Blessed Hope, the appearing of the Great God and Savior, Jesus Christ.
It’s easy to dismiss out of hand, but have you looked into the fact that the first four Jewish feast days were fulfilled? In fact the Passover was fulfilled by Christ to the very hour — 3:00pm
Have you looked into that phrase “no man knoweth the day nor the hour” and seen that this was a common idiom for the next scheduled feast day, Yom Teruah?
Did you know that the “Last Trump” spoken of by Paul is the 100th trumpet blast of Yom Teruah?
Paul refers to the twinkling of an eye, did you know that this was also a Hebraism?
>>>But you, brothers and sisters, are not in darkness so that this day should surprise you like a thief.
