Some Christians struggle over the verse “pray without ceasing” [I Thess 5:17]. John Wesley’s comments suggest that the loving attitude of our heart toward God and others can fulfill this command.
Whether we think of, or speak to, God, whether we act or suffer for him, all is prayer, when we have no other object than his love, and the desire of pleasing him.
Prayer continues in the desire of the heart, though the understanding be employed on outward things.
In souls filled with love, the desire to please God is a continual prayer.
