The vision if isaiah of the two riders in Isaiah 21:7:
"And he saw a chariot with a couple of horsemen, a chariot of asses, and a chariot of camel...."
Who was the rider upon an ass? every Sunday School student will know him. That was Jesus (pbuh) (John 21:14):
"And Jesus, when he had found a young ass, sat thereon; as it is written."
Who then is the promised rider on a camel?This powerful prophet has been overlooked by Bible readers. This is the Prophet Muhammad (pbuh). If this is not applied to him, then the prophecy has yet to be fulfilled. That is why Isaiah mentioned further in the same chapter(21:13);
"The burden upon Arabia...."
..which means the responsibility of the Arab Muslims, and ofcourse now all Muslims,to spread the message of Islam!!
