S: Revelation 15:1-4 Then I saw in heaven another marvellous event of great significance. Seven angels were holding the seven last plagues, which would bring God’s wrath to completion. I saw before me what seemed to be a glass sea mixed with fire. And on it stood all the people who had been victorious over the beast and his statue and the number representing his name. They were all holding harps that God had given them.
And they were singing the song of Moses, the servant of God, and the song of the Lamb: “Great and marvellous are your works, O Lord God, the Almighty. Just and true are your ways, O King of the nations. Who will not fear you, Lord, and glorify your name? For you alone are holy. All nations will come and worship before you, for your righteous deeds have been revealed.”
O: Things are in chaos on earth at this point in Revelations. However, the saints in heaven see that God is still in control.
It's like when we are reading a gripping novel where the protagonist faces all sorts of trials and tribulations, but someone who has already read the novel mentions to us that the protagonist will survive and succeed in the end. So even while we are in the midst of the novel and the protagonist is in great peril, we still know that, in the end, he will win.
Well, we've read the end of the book! We know that God will prevail in the end, and we who are with God will prevail with Him! Those saints in heaven who "had been victorious over the beast and his statue and the number representing his name" died for their faith under Nero's persecution. But we now see them in heaven rejoicing and singing praises to God!
A: So, even while we go through trials and tribulations on earth, we can be assured that we just have to stay faithful to Jesus, and it'll all work out in the end. Even in persecution comes and we are killed physically for our faith, there is nothing they can do to us ultimately!
P: Great and marvellous are Your works, Lord God Almighty! Just and true are Your ways, O Lord! For you are the King of Saints! Who shall not fear You? Who shall not glorify Your name O Lord? For only You are worthy! All the nations shall come and worship before You! For Your judgements are made manifest! Hallelujah! Amen!
