The Psalms has been the songbook of the worshiping people of God. It's been their response to the LORD, for who he is and what he has done, expressed in a range of emotions. That's why there are hymns of praise as well as songs of lament, like Psalms 42 & 43. Taken together, they can give voice to your feelings of grief, doubt, or despair and can point you towards greater hope and healing.
