One of the greatest description in the Bible
is the vision that John was shown of the
return of Jesus Christ.

"And I saw heaven opened and, behold, a
white horse; and he that sat upon him was
called Faithful and True, and in righteousness
he doth judge and make war. His eyes were
like a flame of fire, and on his head were crowns;
and he had a name written, that no man knew,
but he himself. And he was clothed with a vesture
dipped in blood; and his name is called The Word
of God.
And the armies that were in heaven followed him
upon white horses, clothed in fine linen, white
and clean. And out of his mouth goeth a sharp
sword, that with it he should smite the nations,
and he shall rule them with a rod of iron; and he
treadeth the winepress of the fierceness and wrath
of Almighty God. And he hath on his vesture and
on his thigh a name written, King of Kings, and
Lord of Lords," Revelation 19:11-16
