revelation in a paragraph

Here is an excellent summary of the book of Revelation:

"The book of Revelation emphasizes the sovereign control of God over all reality. Not only does G0d, through the person and work of Jesus Christ, govern all human history, but he also gathers up all the apparently loose threads of reality in the glorious consummation of his purposes. The focus of Revelation is the gospel of the Lamb of God. The key to reality is the 'Lamb standing, as though it had been slain' (Rev 5:6). He alone is able to open the scroll and reveal the truth of God's kingdom. Here indeed is the magisterial hermeneutic. The almost oppressive emphasis on judgment in this book reminds us of the accountability of the human race before God. Accountability means that truth is there to be understood and received. Accountability also means that the final reference point for understanding and interpretation is the one before whom all are accountable. The beatific vision of the new heaven and the new earth belongs to those who have washed their robes in the blood of the Lamb (Rev 5:9-14; 7:13-17; 12:11)."
