J.R. Miller on prayer

Those who learn to pray in this way, communing with Christ continually, are sure of rich blessing in their life. Prayer makes us stronger. It brings the divine life down into our heart. It shelters us amid temptation. It keeps us near the heart of Christ in time of sorrow or danger. It transforms us into the beauty of the Master. Prayer brings heaven close about us, into our heart. Prayer keeps us close to Christ; one who prays daily, and continues instant in prayer, will never drift far from Him. It is when we begin to omit prayer that we begin to omit Christ.
