The seventh trumpet blows, signaling the big event when the day of wrath collides with the rage of nations. The temple on earth opens and the ark of the covenant is revealed. The kingdom of this world becomes the kingdom of Hashem and his Messiah. In this study of Revelation 11:14-19, the seventh trumpet blast initiates a process whereby the kingdom will be established.
And it came to pass, when the ark set forward, that Moses said, Rise up, LORD, and let thine enemies be scattered; and let them that hate thee flee before thee. (Numbers 10:35)
