These are the meditations of a messy spirituality, the life-affirming ramblings of ordinary people who never intended their thoughts to be published and widely read. These anonymous prayers come from the meek, the poor in spirit, those who hunger and thirst for righteousness. Some of the authors might not even call themselves Christians, but they still believe in prayer and have dared to post their heart cries on the Internet, on university walls, on church walls and, even, on the walls of a brewery.  Readers will appreciate these raw, honest non-religious psalms and lamentations. Full of life, the big and the small things, they address such issues as AIDS, a slice of pizza and rainbows. Or a teenager crying out for help with her compulsion to self abuse, an ex-con meditating on the meaning of freedom and a person contemplating the deep spiritual significance of a cereal package.
