God's promises part1

Today, I'm reminded of God's precious promises....

10But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything in it will be laid bare.^[a]

Calvin in his commentary says…

But the day of the Lord will come Thus divine patience is balanced by justice, and we are told:

a. the certainty of the coming: will come

b. the character of the coming: like a thief

the consequences of the coming: The heavens will disappear with a roar. It will be then clearly seen that nature is far from immutable (unchangeable). Note other references to phsical convulsions as accompanying the day of God. (Isaiah 34:4, 51:6, Mark 13:24-5). The elements seem to be the heavenly bodies in this verse.
