Is there a standard form of the Jesus Prayer? I know it's a prayer that evolved over a long period of time, but what's the most commonly practiced verison today? I've heard two different forms described as the 'standard' version:
1) "Lord Jesus Christ, Son of God, have mercy on me."
2) "Lord Jesus Christ, Son of God, have mercy on me, a sinner."
Is the phrase, "a sinner", a later edition, and to what effect or purpose?
Thanks so much for the help. I'm just beginning to taste the spiritual richness of the Jesus Prayer, and I'm liking it more each day.
God bless,
Chris
