Book excerpt: All Christians believe that their great God and Saviour, Jesus Christ, will one day return. Although we cannot know the exact time of his return, what exactly did Jesus mean when he spoke of the signs of his coming (Matthew 24)?How are we to interpret the prophecies in Isaiah regarding the time when 'the earth will be full of the knowledge of the LORD as the waters cover the sea' (Isaiah 11:9)? Should we expect a time of great tribulation or reformation and revivalbefore the Lord returns?How do we approach this inspired prophetic book? In what way do these approaches affect our interpretation of the thousand years of Revelation 20? Is the devil bound now, and are the saints reigning with Christ?These, and many more questions, are dealt with by the four authors in The Four Keys to the Millennium. The editor, Michael Meiring, also makes an analysis of the four essays, identifying the strengths and weaknesses of each view.
