Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? ~ 2 Peter 3:12
the day of God. The “day of God” is not the same as the “Day of the Lord.” The “day of God” refers to the eternal state, in preparation for which the heavens and the earth are burned up and the new creation is made. It is likely so named because of what Paul had in mind in 1Co 15:28, the eternal glory of the new creation, with God being all in all. When the day of God comes, man’s “day” will be over. The corrupting of the universe by man and Satan will have been terminated and judged, finally and forever.
the heavens will be dissolved. See notes on verses 2 Pe 3:7, 2 Pe 3:10-11. The new world in which righteousness dwells (2 Pe 3:13), requires the Lord to first destroy the old, sin-cursed universe (Rom 8:19-22). ~ MacArthur Bible Commentary
Since Christians now know that there will be false teachers who will appear, twisting and distorting the Scriptures, they should be all the more on their guard. Any time a believer seriously listens to a false teacher, he runs the risk of being led astray (2 Ti 2:14-18; Tit 1:10-16).
There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures. You therefore, beloved, knowing this beforehand, take care that you are not carried away with the error of lawless people and lose your own stability. ~ 2 Peter 3:16-17
