I, John, who also <FI>am<Fi> your brother, and fellow-partner in the tribulation, and in the reign and endurance, of Jesus Christ, was in the isle that is called Patmos, because of the word of God, and because of the testimony of Jesus Christ;
Revelation 1:7 Lo, he doth come with the clouds, and see him shall every eye, even those who did pierce him, and wail because of him shall all the tribes of the land. Yes! Amen!
Revelation 1:8 `I am the Alpha and the Omega, beginning and end, saith the Lord, who is, and who was, and who is coming--the Almighty.'
Revelation 1:9 I, John, who also <FI>am<Fi> your brother, and fellow-partner in the tribulation, and in the reign and endurance, of Jesus Christ, was in the isle that is called Patmos, because of the word of God, and because of the testimony of Jesus Christ;
Revelation 1:10 I was in the Spirit on the Lord's-day, and I heard behind me a great voice, as of a trumpet, saying,
Revelation 1:11 `I am the Alpha and the Omega, the First and the Last;' and, `What thou dost see, write in a scroll, and send to the seven assemblies that <FI>are<Fi> in Asia; to Ephesus, and to Smyrna, and to Pergamos, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea.'
The verse centers on "called", "john", "brother", "fellow-partner", "tribulation", "reign", "endurance", and "jesus". It is saying that the verse draws attention to "called" and "john", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "I am the Alpha and the Omega..." into verse 10's "I was in the Spirit on the...", so "called" and "john" belong inside that flow. In Revelation context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "called" and "john" with trust shaped by these words, not by a vague optimism outside the passage.
