When Will The End of the World Come?
The world itself will not end but will be renewed and remade. In fact, there is also going to be a new heaven according to Revelation 21:1-2. Many people refer to 2 Peter 3:10, where many translations say it will be burned up, whereas other translations render the word discovered (see footnote in your Bible).
Now consider this: Jesus Christ must reign until He has put all His enemies under His feet (1 Cor. 15:25-26). The last enemy that will be abolished is death. Revelation 20:14 says, “And death and Hades were thrown into the lake of fire.” The reward of the saved is co-rulership with Jesus Christ (Rev. 2:26). We will be kings and priests and reign on this earth. If the world is going to be totally destroyed, then God’s plan for redeeming lost sinners would be destroyed. The word of God states, “…world without end” (Is. 45:17, King James Version).
There is only one condition in which the Lord would utterly destroy the world. Malachi 4:5-6 says if Elijah does not come before the great and terrible day of the Lord at the end of the age, the land will be cursed. Elijah’s message will restore broken families and establish the husband and father as head of the family. Children will once again respect their fathers in a godly way. Otherwise, God will smite this earth with a curse and the word curse should be translated “utter destruction.”
