“For the eyes of the Lord run to and fro throughout the whole earth, to show Himself strong on behalf of them whose heart is perfect toward Him” II Chronicles 16: 9. 

From the earliest days of research into hearing impairment, those who studied the matter have told us how much the power of speaking depends on that of hearing, and how the loss of hearing in children can be followed by difficulties with speech. This is true in a wider sense. As all of us hear, so we speak.  It is especially true in the highest sense of our dialogue with God.  To offer a prayer—to give utterance to certain wishes and to appeal to certain promises—is an easy thing and can be learned of man by human wisdom.  But to pray in the Spirit, to speak words that reach and touch God, that affect and influence the powers of the unseen world—such praying, such speaking depends entirely upon our hearing God’s voice.  Just as far as we listen to the voice and language that God speaks, we shall learn to speak in the voice and language that God hears.

Nothing short of praying that prevails with God should ever satisfy our hearts.
