1 Timothy 6:15
1 Timothy 6:1515which the blessed and only Sovereign One—the King of kings and Lord of lords—will bring about in His own time.
JWs read as a direct description of Jehovah the Father alone — "the King of those who rule as kings and Lord of those who rule as lords… whom no man has seen or can see." The "no man has seen" clause is taken as decisive: since Jesus was seen bodily by the apostles, the passage cannot be describing him, and the titles must therefore belong exclusively to Jehovah as the supreme sovereign.
The move is not to contest who is about, but to show what happens when you set it alongside Revelation. The NWT at reads "the King of those who rule as kings and Lord of those who rule as lords" — a literal rendering of the Greek participles (basileuontōn, kyrieuontōn). At and 19:16 the Greek shifts to the genitive plural nouns basileōn and kyriōn, which the NWT renders as "King of kings and Lord of lords." The surface wording differs, but the theological function is parallel: the sovereign-over-all title. reserves "God of gods and Lord of lords" for Jehovah as the supreme being, not merely the highest of many kings. The pattern: a title structure the Old Testament reserves for Jehovah, which Paul uses of the Father in and Revelation gives to the Lamb — in the JW's own Bible.
The question to ask gently: "If 'King of kings and Lord of lords' in describes the one true sovereign, and your Revelation calls the Lamb by that same title, what category does the Lamb belong in?" The "no man has seen" clause describes the Father's unapproachable divine nature — which says the Son has "explained" by making that nature visible in the incarnation. The passages work together, not against each other.
