“And they *sang a new song, saying, “Worthy are You to take the book and to break its seals; for You were slain, and purchased for God with Your blood men from every tribe and tongue and people and nation. You have made them to be a kingdom and priests to our God; and they will reign upon the earth.” (Revelation 5:9-10 NASB)
Think on the prophetic vision set forth here. The Lamb is worthy. The Lamb was slain. The Lamb purchased. The purchase was for God. The purchase was humans; these humans are from all ethnic groups and languages and nations. This is universal and global; it is beyond local, provincial and tribal! These purchased humans were made into a kingdom. All became priests to God. These redeemed will reign, not in Heaven, but right here on this earth.
