Charles Ellicott Commentary Matthew 24:35

"Heaven and earth shall pass away, but my words shall not pass away." — Matthew 24:35 (ASV)

Heaven and earth — The tone is that of One who speaks with supreme authority, foreseeing, on the one hand, death and seeming failure, but on the other, the ultimate victory—not of truth only in the abstract, but of His own word as the truth. The parallelism of these words with those of Psalm 102:26 and Isaiah 40:8 gives them their full significance. The Son of Man claims for His own words the eternity that belongs to the words of Jehovah (Compare to 1 Peter 1:24–25).

The whole history of Christendom witnesses to the fulfillment of this prophetic claim. Amid all its changes and confusions, its errors and its sins, the words of Christ have not passed away but retain their preeminence as the last and fullest revelation of the Father.
