You must learn to pray from your heart and not your head. The mind is so limited in its operation that it can only focus on one object at a time. Prayer offered from the heart cannot be interrupted by reason. Nothing can interrupt this type of prayer. When you have enjoyed God and the sweetness of His love, you will find it impossible to set your affections on anything other than Him. There must be a hungry heart, willing to yield before it can receive. God desires to give His presence.
