The ebook The Power of the Spirit by William Law details the power and work of the Holy Spirit. Law provides a concise yet instructive and challenging exposition of the Holy Spirit. Andrew Murray claimed, ”In all my reading I have never found anyone who has so helped me in understanding the Scripture truth of the work of the Holy Spirit.” Christians must depend, Law explains, on the constant leading of the Spirit and can enjoy that leading without interruption. This edition is edited for today's reader by David Hunt.

William Law taught at Cambridge in the early 1700s, but was banned from preaching because he refused to take an oath of loyalty to the Hanoverian dynasty. He preached through his books which impacted later Christian leaders like John and Charles Wesley and George Whitefield.
