Charles Cooper has written an E-Pamphlet, Revelation 3:10: A Bombshell.
Revelation 3:10 – A Bombshell is a compilation of quotes by the leading teachers of the pretribulation rapture position concerning their view of the significance of Revelation 3:10. Many have explicitly stated that this verse proofs the timing of the pretrib rapture. In this pamphlet, after allowing each man to state in his own words his conviction that Revelation 3:10 is a proof-text, Cooper then shows how a fellow pretribber completely demolishes their arguments.
