God wants your heart. The whole Bible teaches truth and awakens emotions, but the Psalms are in a category of their own. They do not just awaken heart; they put it in the foreground. They do not just invite our emotions to respond to God's truth; they put our emotions on display. The Psalms are not just commanding; they are contagious. We are not just listening to profound ideas and feelings. We are living among them in their overflow. We touch pillows wet with tears. We hear and feel the unabashed cries of affliction, shame, regret, grief, anger, discouragement, and turmoil. But what makes all this stunningly different from the sorrows of the world is that all of it-absolutely all of it-is experienced in relation to the totally sovereign God. This book is an invitation. God wants our hearts. He will take them as he finds them. And then, with the healing contagion of the Psalms, he will shape them. Accept his invitation to come.
