I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ…
Whenever a man is sent anywhere for the Word of God and the testimony of Jesus Christ, he is not in prison, he is not in Patmos only. Jesus Christ said "the Son of Man who is in heaven" at the very moment when He was sitting upon the earth and was visible to spectators; and so John might have said — I was in Patmos yet I was in heaven; in the body I was confined to a bruited island, but in the spirit I was with my Lord in the sanctuary of the skies, lost in contemplation and adoration, and preparing to return to the earth with fuller equipment as a gospel preacher.
(J. Parker, D. D.)
