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 its consummation in Christ. If you read it with that main point in mind, you will be able to understand it. You will not necessarily understand ever detail - neither do I. But it is not necessary to understand every detail in order to profit spiritually form it. Vern Poythress, The Returning King, p. 11.
