Chapter 178

The Jesus Prayer in Full and in Parts

Pray every Jesus Prayer in full: “Lord Jesus Christ, Son of God, have mercy on me, a sinner!” and also in parts: “Lord Jesus Christ, have mercy on me! Jesus, Son of God, have mercy on me!” Pray this great prayer—the most important of the short ones—more often than the others, sometimes in full and sometimes in parts.
