I'm not accusing you of doing this deliberately, but it's quite misleading to the unchurched/uninformed to see people speaking/writing about a theory that's less than 200 years old (dispensationalism), as if it's "the gospel truth".
Not all Christians embrace that relatively new viewpoint of eschatology [last things] that Darby concocted and brought to the USA about 140 years ago. Just because dispensationalism is the most widely taught perspective in today's (Tim LaHay, et.al.) pop-culture churches, doesn't make it so.
Here is a much older view than that of dispensationalism:
For instance, the "Amillennialism" view of last things is that the Bible teaches "the end times" began when Christ was crucified, and the New Covenant was instituted, and that there will be a continuous parallel growth of good and evil in this world between the first coming of Christ and the second coming of Christ. The kingdom of God is now present in the world through his Word, his Spirit, and his Church. This is also known as "realized millennialism".
