“Jesus underscores our need to be alone with God [see Matthew 6:6]…. as friends love to share treasured secrets, so the Lord loves to share secrets of His truth, His Triune Person, His kingdom, and His love with believers. Through His Spirit He uncovers scriptural truth more deeply in the soul by means of private prayer. It is between the closest friends that the most is shared: ‘The secret of the Lord is with them that fear him; and he will shew them his covenant’ (Ps. 25:14)” (James W. Beeke and Joel R. Beeke, Developing a Healthy Prayer Life, 11).
