The pain, loss, tragedy & grief we experience in life can suggest that God doesn't care. But, nothing could be farther from the truth, though learning to trust God can be a slow & difficult process. In this book (which comes from a place of personal grief/tragedy, yet is approachable to those who have not experienced deep loss), Jerry Bridges illustrates that God is worthy of our trust -- during the tough times & the rest of the time, too. A 12-lesson Study Guide over this book is also available.
