A new and fully updated edition of Colin Urquhart's major book on the work of the Holy Spirit, for this important time of revival Many churches internationally have been experiencing revival and growth on a huge scale in recent years. Many are indeed praying for a spiritual awakening in their nations. But, Colin Urquhart argues, revival has to begin among Christians themselves. In this biblical call to true holiness, he explains how the fire of the Holy Spirit can work with purifying, refining power among his people, inflaming their hearts with renewed zeal for his purposes. Drawing on his own experience of God's Spirit, and basing his teaching firmly in Scripture, Colin shows Christians how holiness can become a reality in their lives.
