According to the Bible the world, or earth, will never come to an end. The word “world,” which our Lord uses in this connection, does not refer to the earth, or even the people on it. It is the old Greek word aion, or age. Several ages in God’s 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:
“For 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.”
But doesn’t Rev. 21:1 predict “a new heaven and a new earth”? 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:
“He that sat upon the throne: said, Behold I make all things new.”
Note: He didn’t say “I make all new things,” but “I make all things new.” 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 “the dispensation of the grace of God,” 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:
“We then, as workers together with [Christ], beseech you also that ye receive not the grace of God in vain…. Behold, now is the accepted time; Behold, now is the day of salvation” (II Cor. 6:1,2). source
