The reason for praying is so that God will be thanked when the blessings come. And God loves to be thanked. He loves to be acknowledged and praised as the giver of all good gifts. His great goal in history from beginning to end is to be glorified as the source of all blessing. Therefore, when we urge many people to pray for something that we need, we create a situation in which the provision of that need will produce many thanksgivings to God. And in that way we tap into a tremendous incentive that God has, namely, to glorify Himself by winning the gratitude of many people. God loves to be thanked by many people. Therefore, there is a power in church-wide prayer, because the more people there are praying for the spiritual life of our church, the more thanksgiving will ascend to God when He gives it.
