The apostle John is in a prison colony because of his faithfulness proclaiming the gospel. Jesus himself alluded to the fact that this was going to happen:
Matthew 20:20-23 “Then the mother of the sons of Zebedee came to him with her sons, and kneeling down she asked him for a favor. He said to her, ‘What do you want?’ She replied, ‘Permit these two sons of mine to sit, one at your right hand and one at your left, in your kingdom.’ Jesus answered, ‘You don’t know what you are asking! Are you able to drink the cup I am about to drink?’ They said to him, ‘We are able.’ He told them, ‘You will drink my cup…'”
While there, he has a vision of Jesus Christ’s glorious victory over the forces of evil. He reveals this vision to us in apocalyptic language, in symbols and metaphors, and it can be confusing. However, in the midst of all the discussion over what the book of Revelation actually means, trust this: Revelation show that Jesus is God and is coming again! Although the letter itself is sent to seven churches in Asia Minor, the call is for the church as a whole to hear and to be faithful even in the midst of persecution.
Why should we listen? Why should we obey? Why should we be faithful? Because of the majesty and grace of the triune God! The Father, Son, and Holy Spirit are presented as omniscient and all powerful. They are described as “He who is, and who was, and who is still to come,” the “Alpha and Omega,” and “the seven spirits who are before His throne.” Additionally, Jesus is shown as prophet (“faithful witness“), priest (“firstborn from the dead“), and king (“ruler over the kings of the earth“). But He is a servant king, who gave Himself for us and “has set us free from our sins at the cost of his own blood.” Revelation 1:12-18 uses wonderful Old Testament imagery to reveal that Jesus is pure, wise, and divine. He is the righteous judge who has authority over all things, but especially over the church! He is in the midst of her, and He is the one who speaks the Word of God.
Hebrews 4:12 “For the word of God is living and active and sharper than any double-edged sword, piercing even to the point of dividing soul from spirit, and joints from marrow; it is able to judge the desires and thoughts of the heart.“
