2 Peter may finally clinch the matter for our question:

2Pet. 1:18 We ourselves heard this voice come from heaven, while we were with him on the holy mountain.
2Pet. 3:5 They deliberately ignore this fact, that by the word of God heavens existed long ago and an earth was formed out of water and by means of water,
2Pet. 3:7 But by the same word the present heavens and earth have been reserved for fire, being kept until the day of judgment and destruction of the godless.
2Pet. 3:10 But the day of the Lord will come like a thief, and then the heavens will pass away with a loud noise, and the elements will be dissolved with fire, and the earth and everything that is done on it will be disclosed.
2Pet. 3:12 waiting for and hastening the coming of the day of God, because of which the heavens will be set ablaze and dissolved, and the elements will melt with fire? 13 But, in accordance with his promise, we wait for new heavens and a new earth, where righteousness is at home.

This book brings all the themes together:
1. The Voice of God comes from heaven at Jesus’ transfiguration (1:18). Here it is the place of God from which location God acts on earth.
2. God created the heavens (3:5).
3. The present heaven and earth will someday be destroyed (3:7). When? On the day of judgment. This could be the purgation of the earth of its sinful death-shaping directions, but that view is far from easy to demonstrate.
4. The present heaven and earth will be dissolved in a grand act of discerning, revealing judgment (3:10).
5. Then God will refashion it all as a “new heavens and new earth” (3:12-13).
There it is; perhaps the only text in the NT that puts it all together.
But, we’ve got some texts in Revelation for next week. And then we’ll look at the word “gospel” for awhile.
