The rider on the white horse is
JESUS.

Revelation 6:2
And I saw, and behold a white horse: and he that sat on him had a
bow; and a crown (stephanos) was given unto him: and he went forth conquering,
and to conquer.
The first of the four horsemen of the apocalypse.
Although the majority of the commentators teach that
this conqueror is the antichrist -
Henry Morris, among others ,
believe that HE is JESUS ( Revelation Record pg.112 ).
