I have heard Sinclair Ferguson speak before and I have admired his preaching. He is a sound preacher and when I saw this book written by him, I knew I wanted to read it.
As a Christian, I often find myself getting caught up in this world and its struggles and sorrows. I allow these things to overwhelm me and I forget the truths of God's Word. Instead, I listen to the lies of the enemy and lose the joy of my salvation.
