St. Peter passes on to tell of the terrors which shall attend on that day. Here also he has in mind the words of his Master, who, after a prophecy of the destruction of Jerusalem, spake of that greater coming of the Son of man of which the overthrow of the Holy City was to be but a partial type: "There shall be signs in sun and moon and stars, and upon the earth distress of nations, in perplexity for the roaring of the sea and the billows, men fainting for fear and for expectation of the things that are coming on the world, for the powers of the heavens shall be shaken" (Luke xxi. 25; Matt. xxiv. 29). With the Lord's language for his warrant, he paints, largely in the words of the prophets of old, the things which shall befall the world in that great and notable day: _In the which the heavens shall pass away with a great noise, and the elements shall be dissolved with fervent heat, and the earth and the works that are therein shall be burned up_. Isaiah had used like words of old: "All the host of heaven shall be dissolved, and the heavens shall be rolled together as a scroll" (Isa. xxxiv. 4); and in another place he speaks (xxiv. 19) of the earth as utterly broken, clean dissolved, moved exceedingly; Micah has to proclaim the coming of the Lord, and he pictures it thus: "The mountains shall be molten under Him, and the valleys shall be cleft as wax before the fire" (Micah i. 4); and Nahum, describing the day of the Lord which he foresaw was coming upon Nineveh, says, "The mountains quake at Him, and the hills melt; and the earth is upheaved at His presence, yea the world and all that dwell therein." It is St. Peter's, by the light of the words of Jesus, to read their full purport into these prophetic messages, and to teach those upon whom the ends of the ages are come that all these things will have their consummation in that coming of the Lord which shall be the close of these latter days. When thus considered his description contains many striking details. "The heavens will pass away." Christ Himself had so spoken, not of heaven only, but of the earth also. His word was the same which Peter employs, but He used it in the same sentence thus: "My word will not pass away" (Matt. xxiv. 35). That is the one thing to which we may trust. All else will be destroyed or changed. Only those who are in Christ will be fit for the new order. For them old things are passed away; behold, they are become new (2 Cor. v. 17). They have been purified by the fire of the Holy Spirit, and so can abide the day of Christ's coming.
