Danial 7:25 speaks of Christian persecution during tribulation, why does church speak of rapture?

Those of us who are the true Christians at the rapture, (this has nothing to do with denomination) will be gone. Many will BECOME Christian during the Tribulation. They are the one who are beheaded for their testimony as stated in Revelation 20:4. A great multitude of people will turn to Christ during the Tribulation. a href="http://www.armageddonangelsufos.com" rel="nofollow"http://www.armageddonangelsufos.com/a
