Revelation 15:5-8

5 After this I looked and the sanctuary of the tent of the testimony in heaven was thrown open, 

During the last 3 1/2 years the full and complete Gospel of the Kingdom will be preached to every nation, tongue, and tribe. This is the one sign of Jesus’ return, Mark 13. During these years our Father holds nothing back from His children. We will be empowered as never before to preach the Truth with power and demonstration of the Holy Spirit. We will be used to do the works that Jesus was used to do and even greater ones, John 14:12. We will be perfect, without spot, wrinkle, or blemish, Ephesians 5:27. 

6 And there came out of the temple sanctuary the seven angels bringing the seven plagues (afflictions, calamities). They were arrayed in pure gleaming linen, and around their breasts they wore golden girdles. 

7 And one of the four living creatures [then] gave the seven angels seven golden bowls full of the wrath and indignation of God, Who lives forever and ever (in the eternities of the eternities). 

8 And the sanctuary was filled with smoke from the glory (the radiance, the splendor) of God and from His might and power, and no one was able to go into the sanctuary until the seven plagues (afflictions, calamities) of the seven angels were ended. [I Kings 8:10; Isa. 6:4; Ezek. 44:4.]

This is our Father finishing His plan for the world and no one is able to go into the Heavenly sanctuary until it is complete. This Revelation doesn’t say it directly, but our Father knew that there would be a time in history when people would believe that there would be a pre-tribulation rapture. So we see Jesus here showing John that no one can come to the sanctuary until everything is finished. Our Father also repeatedly shows us in this Revelation that people stand before the throne. But when we are caught up with Jesus, after the last trumpet, we rule and reign with Him. All of the events that we have seen are ordered from the Throne. They are ordered and orchestrated directly from where our Father is and He keeps showing us, we are not physically, even though we are spiritually, there with Him until the events of His wrath are finished. 

The Holy Spirit tells us in Ephesians 2:6 that we have been raised up together and made to sit together in Heavenly places in Christ Jesus. Our spirits are in the Throne right now with our Father, but our bodies are still here on the earth. This is why John always sees us in front of the Throne and not in it. 

I really cannot write this enough: our Father does not abandon Grace during the great Tribulation. Miracles, revelation, and salvation will abound through the saints.
