Hi, Lizzie -
I would submit that one can take a more positive, nurturing view of the Lord's Prayer. If your perspective of the Christian God is of a loving, nurturing, supporting, forgiving Being of nonspecific gender, then the Lord's Prayer can be quite positive.

If you see God as the One who forgives when no one else will forgive, that's a pretty big thing. If you see God as the Source of all Goodness, that's pretty big, too. Remember that St. John said God is Love. That puts a different spin on it, too.

The authoritarian view of God is not the only valid Christian perspective - and I don't think it's the view of God that Jesus had.
