He then indicates the specific timeframe for the fulfillment of His prophecy, stating, “This generation shall not pass away, till all these things be fulfilled,” meaning that the events would indeed commence within that generation, which came to fruition when Jerusalem was destroyed forty years later, in AD 70. Furthermore, the Lord emphasizes the certainty of His prophetic word, asserting that heaven and earth would sooner perish than His words remain unfulfilled. After generally outlining the commencement of these prophecies, the Lord continues by declaring, “But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.” The sudden onset of this final day and hour will catch humanity by surprise, akin to how the flood unexpectedly engulfed Noah's contemporaries or how an enemy ambushes a worker, leaving one captured and another spared.
Notes: It is clear that had He stated, “I know,” but refrained from disclosing it, it might have caused them distress. However, by indicating that neither the angels nor He Himself had knowledge of it, He wisely prevents them from seeking or pestering for answers. It is evident that the Lord possesses knowledge of the final day and hour, as He created time itself. While the Son knows all as God, He adopts a posture of ignorance as a part of His humanity, for only the tangible can be distinguished from the abstract.
