The judgments that are listed elsewhere in Scripture seem to contradict God's covenant with Noah. How can the promise of no future divine judgments be reconciled with the fact that God will judge the entire earth again in the future? The Bible says:
But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up (2 Peter 3:10).
Until The End
One possible answer to this question is that God will not judge the entire earth of living things until the final judgment. Those who advocate this view believe that worldwide judgment will be postponed until the time of the end. As evidence of this they point to
Genesis 8:22 that says, while the earth remains which qualifies the statement in
Genesis 8:21. This, however, does not seem to be what the passage is saying. In addition, it contradicts what Scripture says. At the Second Coming of Christ, the earth will again be judged but it will continue to last for another thousand years during the period of the millennium (
Revelation 20). After the thousand years of the millennium, God will create a new heaven and new earth.
Curse Of Flood
The best answer seems to be that God will not judge the entire earth with a
Flood as He did in the days of Noah. The context of this passage is not that God will never judge the world, the idea is that He will never judge the world with a Flood.
Genesis 8:21 speaks of the curse of the Flood, not the curse of
Genesis 3 and the Fall. The context in this passage focuses on the Flood.
Summary
The judgment in Noah's day was unique, never again to occur. The promise of God is that He would not send another Flood to judge the world, not that He would never judge it again. The Bible makes it clear that God will again judge the world.
