Found this interesting thought on the Lord's prayer by Lorraine Kisly. She thinks, (and I am inclined to agree) that the we need the Lords Prayer in Church because it a prayer that turns the "prayer of our daily lives" on its head;
According to her our 'life' prayer goes some what like this:
Master of Earth
Exalt my name over all others.
Give me a kingdom where my will is never thwarted.
Let me take whatever I wish, and grant me vengeance over all who oppose me.
Let me satisfy my every desire,
And give me power to crush anyone who stands in my way...
It's kind of scary, because in spite of all the Holy Spirit's work in me, I still find myself wanting my own way, wanting to be first in everything.
The prayer of Jesus then maybe is more than our daily bread but out daily confession, and inoculation against our 'natural' tendencies..
