Who will be King over all the earth according to this verse?
The verse declares that Jehovah, who is identified in the New Testament as Christ, will be King over all the earth. It presents this as future prophecy, not yet fulfilled, and emphasizes that Jesus Christ Himself will reign universally.
Les explains that the verse is clear prophecy that has not yet happened. He notes that in the Old Testament the Lord is Jehovah, and in the New Testament Jehovah is Christ, as shown in John's Gospel where Jesus said, "Before Abraham was, I AM." Therefore, the promise that Jehovah the Christ shall be King over all the earth points to Christ's future return and universal reign. Les also recounts a pastor who once dismissed the plain meaning of verse 4 as apocalyptic, but later came to see it means what it says—Christ will return and stand on the Mount of Olives.
