New Defender's Study Bible Notes
1:8 Alpha and Omega. There are the first words actually spoken to John by the Lord on this great occasion. Alpha and Omega are the first and last letters of the Greek alphabet, the Lord thereby claiming that He embodies all language and, in fact, all reality. He is “the Word” (John 1:1), embodying “all the treasures of wisdom and knowledge” (Colossians 2:3). He also claims to be the Eternal One and the Omnipotent One. A more definitive claim to absolute deity, made by the glorified Lord Jesus in reference to Himself, could hardly be imagined.
