"The earliest version of this prayer came from a blind beggar named Bartimaeus, who cried out as Jesus was passing by, “Jesus, Son of David, have mercy on me!” (Luke 18: 38). If you add Paul’s Philippian hymn, “confess that Jesus Christ is Lord” (Philippians 2: 11), you’ve got the Jesus Prayer. From the beginning, this prayer was used continuously. When the crowd shushed Bartimaeus, “he cried out all the more” (Luke 18: 39). He must have been shouting at the top of his lungs because three of the gospels mention his loud persistence!
"We needed mercy. That mind-set creates a praying heart. A praying life isn’t simply a morning prayer time; it is about slipping into prayer at odd hours of the day, not because we are disciplined but because we are in touch with our own poverty of spirit, realizing that we can’t even walk through a mall or our neighborhood without the help of the Spirit of Jesus."
