The incident - a rider wearing a crown goes out on a white horse
The identification
Not Christ:
Although Christ rides a white horse in chapter 19, He doesn't bring famine,
pestilence and war in His wake
The events of Revelation are chronological and Christ comes to conquer at
the end of the tribulation, not the beginning
Not the Anti-Christ
There is a gradual build-up of power for the Anti-Christ
The other horsemen are not people, but conditions which they
symbolize
Thus the first horseman is symbolic of the spirit of the age at the
beginning of the tribulation period - tension and lack of peace, but no outright warfare.
