The passage reads, "And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places." Manifestly, the atmospheric heaven is referred to. The great convulsions of nature attendant on Christ's second coming seem to affect the atmosphere to an extent hitherto unknown. Just what is meant by that expression nobody can explain. The most terrific convulsions of nature which have taken place do not approach in calamity or majesty or direfulness what will then take place in this earth, with the weight of sin resting upon it and the restraining power of God withdrawn. To those who are then upon the earth it would seem as if everything were swiftly tending to utter and overwhelming destruction.
