Over the centuries, much has been said and written about the Jesus Prayer. And with good reason! In a concise manner, praying “Lord Jesus Christ, Son of God, have mercy on me, a sinner” (or one of its variations) helps us to follow the Apostle Paul’s exhortation to “pray without ceasing” (Thessalonians 5:17). The greatest commandment—that we love God with all of our heart, soul, mind, and strength—requires from us a steadfast effort to keep Him in the forefront of our conscience—and this is through the work of continual prayer. The more we pray, the more we are mindful to live according to God’s will.
