Commentaries:
Jamieson, Fausset, and Brown
Heaven and earth shall pass away; but my words shall not pass away—the strongest possible expression of the divine authority by which He spake; not as Moses or Paul might have said of their own inspiration, for such language would be unsuitable in any merely human mouth.
Warnings to Prepare for the Coming of Christ Suggested by the Foregoing Prophecy (Mark 13:32-37).
It will be observed that, in the foregoing prophecy, as our Lord approaches the crisis of the day of vengeance on Jerusalem and redemption for the Church—at which stage the analogy between that and the day of final vengeance and redemption waxes more striking—His language rises and swells beyond all temporal and partial vengeance, beyond all earthly deliverances and enlargements, and ushers us resistlessly into the scenes of the final day. Accordingly, in these six concluding verses it is manifest that preparation for "THAT DAY" is what our Lord designs to inculcate.
