Revelation 1:2

And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him.

The people therefore that was with him when he called Lazarus out of his grave, and raised him from the dead, bare record.

And he that saw it bare record, and his record is true: and he knoweth that he saith true, that ye might believe.

This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.

Even as the testimony of Christ was confirmed in you:

And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God.

I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ.

And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:

And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
