For just then the seventh angel blew his trumpet, and there were loud voices shouting down from heaven, “The Kingdom of this world now belongs to our Lord, and to his Christ; and he shall reign forever and ever.”
Revelation 11:15 TLB
What will happen in the "blink of an eye" in this world has been planned from the beginning of Creation. Seven is the number of completion. Just as God created the earth and all that exists within it and rested on the seventh day, He has used this number throughout Scripture to designate the end of a period of time. Yet, with God, the end of something is often the beginning of something else. When that seventh horn blows, Jesus will begin His reign forever and this time will never end. That's what we have to look forward to.
