Matthew 24:35

“Heaven and earth will pass away, but my words will not pass away.”

And all that He has said is more certain and sure than the continuation of Heaven and earth. We learn here Jesus' awareness both that Heaven and earth will one day pass away, and that His own words have a permanence that reaches into eternity. From this again we recognise the uniqueness of Jesus. Not even the prophets had dared to make a claim like this. But He then immediately goes on to point out that while He is here on earth and aware of all that will in the future occur on earth, there is one thing of which He is not aware, the time when He will come again, and when all things in Heaven and earth will come to an end.
