Revelation 10 is part of the preamble before the seventh trumpet is blown heralding the 7 bowl judgments. The mighty angel here also tells us that when that happens, God's mysterious plan would be fulfilled. The apostle Paul actually already told us about this plan; "God has now revealed to us his mysterious will regarding Christ—which is to fulfill his own good plan. And this is the plan: At the right time he will bring everything together under the authority of Christ—everything in heaven and on earth.
"
Ephesians 1:9-10 NLT. This period will be the right time and when the bowl judgments happen, everything and everyone will be submitted to and be united under Christ.
