Q&A: Mark of the Beast, Gay Marriage, and Biblical Metaphor

On today’s Bible Answer Man broadcast Hank answers questions on the following topics:

What makes the idea of a future mark of the beast and a New World Order incorrect? Isn’t much of the language of Revelation metaphorical?
Is it okay for Christians to attend a gay wedding? How does one approach this subject biblically?
If we refuse to attend their weddings, how then can we reach them for Christ?
Can you clarify your comments on the mark of the beast being metaphorical? I have been taught all my life that it was a literal mark.
