"God wins. If I had to summarize the message of Revelation in just two words, those would be my choice. They not only convey the point of the book but also hint at its main storyline. Despite what some overly speculative interpreters would have us believe, the main character in the last book of the Bible is not the Dragon, Beast, or False Prophet; rather, it is God. Revelation is primarily about Christ, not the Antichrist. And the main point of the book is to demonstrate in graphic imagery the victory of God in Christ.
Through the incarnate ministry of His Son, God has conquered the Devil and his demons; the world and its deceptions; and sin and its destruction. Through faith in Him, we are also victorious over all these enemies. Because He wins, we also win. His victory secures ours. This truth provides fuel for an ever-increasing joy on the part of every believer.
But there is no victory without a contest, and Revelation makes it very clear that the battle between those who belong to Christ and those who oppose Him is real, intense, and deadly. The Devil never simply forfeits. Just as our Lord did not
secure our salvation without severe trials and suffering, so His disciples should not be surprised when their devotion to Him invites brutal conflict.
… The most effective soldier is the one who fights with a clear objective and an unshakeable confidence that victory is
assured. Revelation gives us both for the spiritual warfare we must endure. The mission of the church was mapped
out by Jesus’ first coming. As the sacrificial Lamb, He was slain on the cross, and by His blood He “ransomed people for God from every tribe and language and people and nation” and “made them a kingdom and priests to our God, and they
shall reign on the earth”(5:9–10).
Through His sufferings, our Savior secured the complete redemption of a vast multitude of people that “no man could number” (7:9). Our responsibility is to get the good news of His saving work to these people so that they can be reconciled to God through faith. Sometimes, discharging this duty can be costly.
If Jesus shed His blood for individuals from every people group in the world, how can we who have been rescued by Him remain indifferent in the face of more than six thousand ethnolinguistic groups that have yet to be reached with the gospel? News of our great Savior and His redeeming exploits must be spread to the ends of the earth. Yes, the mission is
dangerous. There will be casualties — martyrs who will be killed “for the word of God, and for the testimony” they bear (6:9–11). But the suffering of Christ’s followers will not be in vain because His kingdom will prevail. Victory is assured."
