And according as a man apprehends Christ in his undertakings and offices, so he will wrestle with and supplicate God. As, suppose a man believes that Christ died for his sins; why, then, he will plead that in prayer with God. Suppose, also, that a man understands that Christ rose again for his justification; why, then, he will also plead that in prayer; but if he knows no more, no further will he go. -John Bunyan, The Work of Jesus Christ as an Advocate
