Importunity is a condition of prayer. We are to press the matter  not with vain repetitions  but with urgent repetitions. We repeat  not to count the times  but to gain the prayer. We cannot quit praying because heart and soul are in it. We pray "with all perseverance." We hang to our prayers because by them we live. We press our pleas because we must have them  or die.
