From Sojourners:
The Psalms defy our notions of profane and sacred, proving that everything we feel, witness, do unto others, and have done to us is acceptable subject matter for conversing with the Divine. They invite us to bring every part of ourselves into our houses of worship. If we omit expressions of faith lost, of rage, of disdain, and of the desire for revenge, we leave parts of ourselves at the door.
