Prayer, originally, is not the work of man alone. Neither is it performed for his comfort or for the fulfillment of his needs or demands. The greatness of prayer lies in its being the work of spiritual beings in general. It is neither of this age, nor for this age. Thus, if we restrict prayer to the satisfaction on man’s needs and demands or to responding to his pleas in this life, it loses its essential greatness. Through hallowing the name of God, paying homage to him, thanking and honoring him with pure praise, man is transformed into a spiritual being. He thus joins the heavenly host in their transcendent ministry.
However, we ask God for temporal things because we have fallen from our original spiritual status in which we lacked nothing. Although this is alien to the original concept of prayer, God in his graciousness has come down to our level and promised to listen to our prayers when we bring him our needs and complaints, which he knows only too well. He thus assures us that he will never abandon us for our sins and that our tribulations are a matter of concern to him.
