Jesus's use and understanding of repetition

Jesus prays twice for the blind man in Mk 8, Jesus prays the same thing, over and over again in the garden in Mt 26.  In Luke 18 the widow is pointed to as an example of good prayer and she kept saying, "Give me justice and avenge me of my enemies."  Take note of what is good and what is considered prayers of faith as we enter a critical year of 2009.
