According to Bishop J. C. Ryle:
A right heart is a PRAYING heart. It has within it “the Spirit of adoption whereby we cry, Abba Father” (Rom. 8:15). Its daily feeling is, “Your face, Lord, will I seek” (Psalm 27:8). It is drawn by an habitual inclination to speak to God about spiritual things—weakly, feebly, and imperfectly perhaps—but speak it must. It finds it necessary to pour out itself before God, as before a friend, and to spread before Him all its needs and desires. It tells Him all its secrets. It keeps back nothing from Him. You might as well try to persuade a person to live without breathing, as to persuade the possessor of a right heart to live without praying.
