Such biblical texts speak of how the present age will end dramatically and how God will set everything right, bringing justice into the world and beginning a new age. Christ's new Kingdom of love and light will be established and the new age begun. Most scholars resist an ultra-literal reading of these texts and with good reason. If you compare the end time Scriptures literally from Isaiah, Ezekiel, Daniel, Mark, Thessalonians, The Revelation, and elsewhere, their sequences of events simply do not match up. Usually such scenarios identify features of current world history as specifically foretold by Scripture and as signs of the end.
Some scenarios actually encourage irresponsibility in our present world.
Mainstream scholarship approaches apocalyptic texts in a different fashion. Written in an age before visual special effects, the Apocalyptic writing style uses descriptions of light, sound and vivid imagery to impress the reader with the seriousness of the author's subject and intent. However, scholars recognize that the Apocalyptic style of writing is a warning about the final judgment and instruction regarding the establishment of Christ's Kingdom, but is not intended to be an exact preview of coming historical events. By contrast, some Christian groups have given themselves over almost completely to elaborately contrived scenarios and horror movie style depictions of God's plans for the end of this present age. Most mainline churches, suspicious of doomsday prophets, remain quiet, generally avoiding reading or talking about these Scriptures.
