Prevailing Prayer
The history of God's ancient people furnishes us with many encouraging examples of prevailing prayer. When the Amalekites came to attack the camp of Israel in the wilderness, Moses knew that his people were not prepared for the encounter. He sent Joshua with a band of soldiers to meet the enemy, while he himself, with Aaron and Hur, took his position on a hill overlooking the battle-field.
There the man of God laid the case before Him who alone was able to give them the victory. With hands outstretched toward heaven, Moses prayed earnestly for the success of the armies of Israel. It was observed that while his hands were reaching upward, Israel prevailed against the foe; but when through fatigue they were allowed to fall, Amalek prevailed. Aaron and Hur stayed up the hands of Moses, until victory, full and complete, turned upon the side of Israel, and their enemies were driven from the field.
This instance was to be a lesson to all Israel to the close of time, that God is the strength of his people. When Israel triumphed, Moses was reaching his hands toward heaven, and interceding in their behalf; so when all the Israel of God prevail, it is because the Mighty One undertakes their case, and fights their battles for them. Moses did not ask or believe that God would overcome their foes while Israel remained inactive. He marshaled all his forces and sent them out as well prepared as their facilities could make them, and then he took the whole matter to God in prayer. Moses on the mount was pleading with the Lord, while Joshua, with his brave followers, was below, doing his best to meet and repulse the enemies of Israel and of God. GW92 31-32
