I will now look at John 1:1. Does “God” as applied to the Logos in John 1:1, provide a basis for calling Jesus “the Lord God” in Revelation 1:8?
No, John 1:1 does not use the expression used in Revelation 1:8, nor does it say that Jesus is "the Almighty". Likewise, in the expressions in which Jesus is referred as "lord", not once do we find him being spoken of with the expression used in Revelation 1:8. It was “Jehovah God” -- the Lord Jehovah (Isaiah 61:1) -- who made Jesus both Lord and Christ (Anointed One), as shown by the expression “Jesus Christ” in Revelation 1:5.
The Spirit of the Lord Jehovah is upon me; because Jehovah hath anointed me. -- Isaiah 61:1, American Standard Version.
Acts 2:36 ASV Let all the house of Israel therefore know assuredly, that God hath made him both Lord and Christ, this Jesus whom ye crucified.
