Can the book of Revelation be understood? Yes it can. Its message can be summarized in one sentence: God rules history and will bring it to consummation in Christ. If you read it with that main point in mind, you will understand it. You willnotnecessarily understand every detail – neither do I . But it is not necessary to understand every detail to profit spiritually from it.
The same thing is true of all Scripture.scripture is inexhautibly rich, so that we can never plumb all its depths and mysteries. But the main points are clear, so we can know how to believe and act.
