Charles Spurgeon Commentary Revelation 1:10-11

"I was in the Spirit on the Lord`s day, and I heard behind me a great voice, as of a trumpet saying, What thou seest, write in a book and send [it] to the seven churches: unto Ephesus, and unto Smyrna, and unto Pergamum, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea." — Revelation 1:10-11 (ASV)

I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet. Saying, I am Alpha and Omega, the first and the last: (Revelation 1:10–11)

What evidence we have here of the divinity of Christ, for we shall see, as we read on, that it is Christ who is speaking here; and just now it was the Father who in much the same words said, "I am Alpha and Omega." We cannot always draw the line between the voice of God and the voice of the God-man, Christ Jesus, and we need not wish to do so, for Holy Scripture does not impose rigid distinctions on us, but desires us to believe it nonetheless. Yet it is always accurate, always true, where it presents shades of definition; for, after all, Christ is so truly God that whether Scripture speaks of Him absolutely as God, or of Him as God and man, Mediator, it matters little to us.
