According to the Bible the world, or earth, will never come to an end. The word βworld,β which our Lord uses in this connection, does not refer to the earth, or even the people on it. It is the old Greek wordΒ aion, or age. Several ages in Godβs program have already come to an end, and others will, but no matter what destructive weapons man may devise, the earth will never be destroyed. In Isaiah 45:18 we read:
βFor thus saith the Lord that created the heavens: God Himself that formed the earth and made it; He hath established it; He created it not in vain; He formed it to be inhabited: I am the Lord, and there is none else.β
But doesnβt Rev. 21:1 predict βa new heaven and a new earthβ? Yes, but the context clearly indicates that this refers to the future renewing of the present heaven and earth, not the creating of different ones. Verse 5 says:
βHe that sat upon the throne: said, Behold I make all things new.β
Note: He didnβt say βI make all new things,β but βI make all things new.β There is a difference.
We should not be concerned about the end of the world, but rather about the end of this present age in which we live under βthe dispensation of the grace of God,β for God has never promised how long this will last. Every hour He delays the return of Christ to recall His ambassadors, is an hour of wonderful grace, in which men may be saved by grace, through faith in Christ who died for our sins. This is why Paul urges us:
βWe then, as workers together with [Christ], beseech you also that ye receive not the grace of God in vainβ¦. Behold, now is the accepted time; Behold, now is the day of salvationβ (II Cor. 6:1,2). source
