The heart's four chambers can be said to mirror four aspects of God's glory - and how our spiritual hearts should beat in time with Him. Discovering how to set our hearts on fire takes us from the disciples on the Emmaus road to God's return. With solid biblical teaching and practical examples, Jeremy guides us to an understanding of how God would have us live: 'Our hearts are the control systems of our spiritual lives - getting them to beat in time with God will transform our attitudes.'
