Of Matthew 24:35 James Morrison, in his commentary on Matthew observes,
“What an immeasurable height here must have been within the self-consciousness of our Lord, when he thus contrasted the imperishableness of his own words with the perishableness of the heaven and earth! It is to his prediction in the preceding verse that he specially refers. Its fulfillment might be absolutely depended on. It would not fail. It was not liable to any casualty or transformation. And what was true of the words of this prediction, is equally true of all our Savior’s words,–of the sum total of his teachings. ‘The grass withereth, and the flower thereof fadeth away,’ the sun and moon and stars shall pass away, ‘but the word of the Lord endureth forever.'” (1 Pet. I, 25.)[1]
