<br> Seven-headed dragons, beasts out of the sea, the marriage of the Lamb - the book of Revelation has fascinated and bewildered Christians for centuries. In every age people have felt sure John described events in their time. As nations arm themselves for war, we think of Armageddon. As evil rulers grow in power, we look for the antichrist. As the powers of darkness threaten to overwhelm us, we cry: "Come, Lord Jesus!" Amid the uncertainties of our modern age, Revelation assures us of the ultimate triumph of God.
