What does Revelation 1:5 mean?
In this verse John describes Jesus Christ as "the faithful witness," because He is the truthful, reliable source of what is recorded in this revelation.Jesus conquered death and arose from the grave. He was the first to rise from the dead in a glorified, everlasting body. As such, He is referred to as "the firstborn of the dead." His resurrection guarantees the resurrection of believers of the church age (1 Corinthians 15:12–28; Philippians 3:11; 1 Thessalonians 4:16), the resurrection of tribulation martyrs (Revelation 20:4–6), the resurrection of Old Testament believers (Daniel 12:2), and the resurrection of the wicked dead of all periods of history (Revelation 20:12–13). Someday He will return to earth and reign over the nations. At that time every king will submit to His rule.
John points out that the ruler of kings is the believers' redeemer. In His deep love for us He shed His blood on the cross to end sin's tyranny over us.
