anyone know why we say "me" instead of "us" during the prayer?
I would think because the Jesus Prayer is based on the Prayer of the Publican, but also because it's a private, personal prayer. While it's certainly laudable to pray for "us," one must also not to forget to pray for "me."
Yes agreed. Also I think it adds the importance of recognizing your own sins before God, and not dissolving into the group of sinners. "It's my sins before you", rather than "I'm just one of the gang". (LOL) so to speak.
