Prayer Tunes Your Heart

Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away. But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory. None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory. But, as it is written, "What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him"- these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. - 1 Corinthians 2:6-10

Self-forgetful, warm, at peace, and filled with interest.

“Prayer also is “a kinde of tune.” Prayer tunes your heart to God. Singing engages the whole being—the heart through the music as well as the mind through the words. Prayer is also a tune others can hear besides you. When your heart has been tuned to God, your joy has an effect on those around you. You are not proud, cold, anxious, or bored—you are self-forgetful, warm, profoundly at peace, and filled with interest. Others will notice. All “heare and fear.” Prayer changes those around us.” Prayer - Tim Keller
