Revelation 1:11 saying, “I am the Alpha and the Omega, the First and the Last,” and, “What you see, write to the seven churches which are in Asia: to Ephesus, to Smyrna, to Pergamos, to Thyatira, to Sardis, to Philadelphia, and to Laodicea.”
Verse 11 repeats what Christ spoke in verse 8, further confirming that it is the Lord Jesus Christ and not God the Father speaking with John. How do we know this? In verse 1 John records that this is the Revelation of Jesus Christ, which the Father gave to Him to show John. In verse 12, John turns to see who spoke to him, and beholds the glorified Christ, fulfilling the Father’s will by revealing these things.
