Verse 2: "And I saw, and behold, a white horse, and its rider had a bow; and a crown was given to him, and he went out conquering and to conquer."

White symbolizes purity. It is without flaw. In this case it symbolizes the pure religion of God. The horse symbolizes power and great strength. The rider is a Knight of Baha'u'llah. He was knighted by Shoghi Effendi in March of 1954 as a Knight of Baha'u'llah. He has a bow (it didn't say he had any arrows). This bow is the symbol of the Covenant: "I set my bow in the cloud, and it will be a sign of the covenant between me and the earth" (Genesis 9:1).
