Revelation 19:11, 16
Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war.
And He has on His robe and on His thigh a name written: KING OF KINGS AND LORD OF LORDS.
The imagery of the horse in biblical times was primarily a vehicle of war. I am always encouraged to know that the LORD is always prepared to fight all our battles on our behalf. He tramples upon all our enemies that come against us in this life. Victory is ours when our LORD is on our side.
