As it is written in the prophets, Behold, I send my messenger before your face, which shall prepare your way before you.
In the East, few good roads are ever made; and such roads as have been made are generally kept in most wretched repair. Hence, when a sovereign is about to visit any part of his dominions, it is requisite that a messenger be sent on before to get the way made ready. Such, in things spiritual, was John's mission. Men's ways were in a wretched state. Encumbrances and stumbling blocks lay everywhere scattered about. Mud and mire were the order of the day. It seemed impossible for anyone to get along through life with unpolluted garments, or without stumbling and falling, and getting bruised and broken. The real preparation that was needed was in the hearts of the people.
(J. Morison, D. D.)
