The central message of this sermon is that the book of Revelation is not primarily about predicting the end of the world or decoding secret codes, but rather it's a revelation of Jesus Christ that seeks to unveil His person and purposes. The key to interpreting the book is found in 1:19, where Jesus instructs John to write what he has seen (a vision of the risen Christ), what is now (the seven churches), and what will take place later (the future events). This message advances the belief that the ultimate focus of Scripture is not on human speculation or curiosity about the future, but rather on understanding and responding to Jesus Christ. The takeaway for listeners is that by grasping this simple yet profound principle, they can approach the book of Revelation with clarity and confidence, knowing that its primary purpose is to reveal the person and character of Jesus Christ, who will be unveiled in all His glory at the end of time.
