Concerning being a Bible Prophecy expert and a Bible Prophecy Guru, I differ from other Bible Prophecy experts in the following ways:
This means that those who take the title as bible prophecy experts or bible prophecy guru's have a great responsibility when we teach of all of the teachings that will occur during the Tribulation such as the Mark of the Beast, the final world empire described in Revelation 13 and many other passages and all of the plagues and judgments of the Revelation.
As a Bible Prophecy Expert and a Bible Prophecy Guru we are to warn of the severity of the events that are going to occur during the Tribulation and warn people how to avoid the Tribulation altogether by accepting Jesus as their personal savior so that they can escape the Tribulation by going up in the Rapture. For those who live during the Tribulation and come to know Jesus as their savior during the seven year Tribulation period, they cannot take the Mark of the Beast because the Mark of the Beast equals death. For those who are Christians and living before the Tribulation begins, they will want to make sure they are 100% living for Christ, because the time left to serve him is short.
So being a Bible Prophecy expert or Bible Prophecy guru is not just about understanding Bible Prophecy and being able to teach it, it is also about teaching the message that is behind, which is a warning to lead one to repentance or to a closer walk with Jesus Christ.
