The great movements of God have had their origin and energy in and were shaped by prayers of men. Prayer has directly to deal with God. Other ends, collateral and incidental, are secured by prayer, but mainly, almost solely, prayer has to deal with God. He is pleased to order His policy, and base His action on the prayers of His saints. Prayer influences God greatly. Moses cannot do God’s great work, though God-commissioned, without praying much. Moses cannot govern God’s people and carry out the divine plans, without having his censer filled full of the incense of prayer. The work of God cannot be done without the fire and fragrance are always burning, ascending and perfuming. Moses’ prayers are often found relieving the terrible stroke of God’s wrath. Four times were the prayers of Moses solicited by Pharaoh to relieve him of the fearful stroke of God’s wrath. “Entreat the Lord,” most earnestly begged Pharaoh of Moses, while the loathsome frogs were upon him. And “Moses cried unto the Lord because of the frogs which God had brought against the land of Egypt, and the Lord did according to the word of Moses.” When the grievous plague of flies had corrupted the whole land, Pharaoh again piteously cried out to Moses, “Entreat for me.” Moses went out from Pharaoh and entreated the Lord, and the Lord again did according to the word of Moses. The mighty thunderings and hail in their alarming and destructive fury extorted from this wicked king the very same earnest appeal to Moses, “Entreat the Lord.” And Moses went out from the city into privacy, and alone with Almighty God, he “spread abroad his hands unto the Lord, and the thunderings and hail ceased, and the rain was not poured out upon the earth.” Though Moses was the man of law, yet with him prayer asserted its mighty force. With him, as in the more spiritual dispensation, it could have been said, “My house is the house of prayer.” Moses accepts at its full face value the foundation principle of praying that prayer has to do with God. With Abraham we saw this clearly and strongly enunciated. With Moses it is clearer and stronger still if possible. It declared that prayer affected God, that God was influenced in His conduct by prayer, and that God hears and answers prayer even when the hearing and answering might change His conduct and reverse His action. Stronger than all other laws, and more inflexible than any other decree, is the decree, “Call upon me and I will answer you.” Moses lived near God, and had the freest and most unhindered and boldest access to God, but this, instead of abating the necessity of prayer, made it more necessary, obvious and powerful. Familiarity and closeness to God gives relish, frequency, point and potency to prayer. Those who know God the best are the richest and most powerful in prayer. Little acquaintance with God, and strangeness and coldness to Him, make prayer a rare and feeble thing.
