[antidisestablishment]

8:21 specifically states that God is suspending his judgement as long as the earth endures (8:22). The span of earth's endurance is not addressed.

Denying the final judgement (Rev 20) is to deny Christ's sacrifice. Is this where you stand?

You make it say something it does not.

You cannot conditionalize a promise based on a following summary of descriptions.

Genesis 8:21 And when the LORD smelled the pleasing odor, the LORD said in his heart,
PROMISE!!
"I will never again curse the ground because of man, for the imagination of man's heart is evil from his youth; neither will I ever again destroy every living creature as I have done.
DESCRIPTION!
22 While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease."

Rev 20 is past. It was judgment on the nation of Israel, not the destruction of all flesh.
He said He would not do that again.
