12 Two Witnesses Put to Death
The sounding of the trumpets shows God's actions in history to bring preliminary judgments on the inhabitants of the earth. As God is seeking to win them to Himself, He issues warnings that the seven plagues will come once He closes the door of opportunity to the world.
Between the breaking of the sixth and seventh seals, there is an interlude to show what is happening to the church. That interlude has been pictured as also occurring between the sixth and seventh trumpets. The church has been called to preach the gospel but in doing so, she faces hostility just as Jesus did.
These events take place while the sixth trumpet is still sounding. They reach down to the time just before the sounding of the seventh trumpet and the consumation of all things.
