Isa 24:14 They shall lift up their voice, they shall sing for the majesty of the LORD, they shall cry aloud from the sea.
Isa 24:15 Wherefore glorify ye the LORD in the fires, even the name of the LORD God of Israel in the isles of the sea.
Those who have heard the gospel of Jesus Christ and have received forgiveness of sins shall lift up their voice, and sing for the glory and majesty of the LORD. "Majesty, worship His Majesty, unto Jesus be all glory, honor and praise." We sing this now, but I believe the church will be remove before the tribulation. There will be people saved during the tribulation, because of the witness of the 144,000 anointed from Israel. The LORD would choose these witnesses and anoint their minds by the Holy Spirit and the word of grace. They will be singing praises in the midst of tribulation.
Rev 7:4 And I heard the number of them which were sealed: and there were sealed an hundred and forty and four thousand of all the tribes of the children of Israel.
The sea, is used metaphorically, as the sea of humanity; they shall cry aloud, from the sea, and it can mean the Islands of the sea.
Isa 24:16 From the uttermost part of the earth have we heard songs, even glory to the righteous. But I said, My leanness, my leanness, woe unto me! the treacherous dealers have dealt treacherously; yea, the treacherous dealers have dealt very treacherously.
The LORD will be glorified by His people throughout the world, but the antichrist Beast, will persecute them. They will not be able to buy or sell and they would be hunted and killed. Many martyrs would come out of the tribulation.
Rev 6:10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
Suffering and persecution has always spread the gospel of Jesus Christ. May we in good times be faithful to him and witness to others.
1 Cor 6:19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
1 Cor 6:20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
