"The LORD also will roar from Zion, and utter His voice from Jerusalem; the heavens and earth will shake; but the LORD will be a shelter for His people, and the strength of the children of Israel." (Joel 3:16)

Between the sixth and seventh trumpets, the Messiah (Deliverer) will physically descend from heaven in a cloud to fulfill the mystery of God, the salvation of Israel (Acts 1:6, Rom. 11:25-27)

"And that He may send Jesus Christ, who was preached to you before, whom heaven must receive until the times of restoration of all things, which God has spoken by the mouth of all His holy prophets since the world began." (Acts 3:20-21)

The restoration of all things is a new heaven and a new earth in which the Lord God will rule forever. (Isa. 65:17, 2 Pet. 3:13)

"There shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light. And they shall reign forever and ever." (Rev. 22:5)

The Lord will begin this restoration by spiritually saving a remnant from Israel (Rev. 10:7, Zech. 14:2). This can't be the coming of the Son of Man which took place after the 6th seal (Mat. 24:29-31). This can't be the appearing of the Word of God which won't take place until the seventh bowl is poured out (Rev. 19:11-21, Dan. 12:11). This can't be the Lamb of God descending in the New Jerusalem which comes forty-five days later (Rev. 21:9-10, Dan. 12:12).
