The first beast is of Revelation chapter 13 is the Roman Empire while second beast with 2 horns like a lamb is the United States of America. The Antichrist is the Man of Sin told in 2 Thessalonians 2, the Babylon is identical with the Whore riding the first beast.
What I understand the rapture and second coming is the same, because Jesus coming will meet first the righteous in the air to give their rewards after that THEY will go down to earth...
You are pre-tribulationist, I dot agree with pre-tribulationist view because the antichrist riding in the first beast already came and will already come to his end!
michae11 you said that the beast having 666 will be worship, but what the Bible says the first beast is to be worship but this beast does not own this mark 666 but only the second beast who got the mark!
