“Heaven and earth will pass away, but my words will by no means pass away.”
~Matthew 24:35

Are Jesus’ words to be taken literally?
The Bible teaches God made the earth to last forever. (Ps. 37:29; Is. 45:18)
In a previous similar statement, Jesus said: “It is easier for heaven and earth to pass away than for one stroke of a letter of the Law to go unfulfilled.” (Luke 16:17)
Jesus was not alluding to a future destruction of the physical universe.
Rather, he was making reference to the opposite.
He was using the permanent nature of the physical world to illustrate how certain the fulfillment of his prophecies is.
In other passages, the phrase “heaven and earth” actually refers to government and mankind. (2 Pet. 3:13)
Jesus was speaking in the context of a coming judgment day, like the one that came through the deluge in the times of Noah. (Matt. 24:37)
Since his kingdom is going to thereafter rule over humans deemed righteous, the current heaven and earth will have come to pass in a symbolic sense. (Matt. 28:18; Eph. 1:19-21)
