The apocalyptic book of Revelation uses symbols and Old Testament references to reveal a pattern of human rebellion and God's plan to overcome evil forever and create a new world.
The book is not a secret code that allows believers to decipher the timeline of Jesus's return. Instead, it shows that every human kingdom eventually becomes Babylon and must be resisted. Jesus, the slain Lamb who died for the sins of the world, will return one day as King with His followers to prompt repentance.
He will remove evil permanently and make all things anew. That promise motivates every generation of God's people to remain faithful in the midst of persecution until their King returns.
