This is prayer for a special need. People are praying for revival in North America. This is a supplication. Supplication moves us in our prayer from the general to the specific. We take a specific need to God and charge him with the responsibility of meeting it.
Prayers are ordinary requests.
Supplications are unique, special requests. Ordinary prayers are presented without a great deal of emotional steam. No one is sick or about to die. Supplication is another matter. Supplication is earnest entreaty about a special need.
