Revelation then, is about the Past and the Future. But it is also about the present, because it is about the people of God living in a hostile and awful world of war and famine and sickness and oppressive government and false religion and immorality and death. And its message will always be relevant, because all those things will be with us till Jesus returns. But he will return, and he will keep us until he does, and that gives us great hope. One more thing needs to be kept in mind as we read Revelation.
Revelation is plain.
It is about the gospel. But it is written in a special style. It is symbolic. Different genres in bible. If I tell you to imagine this scene, you'll probably know what it is I'm describing.
