Amongst the best known of the Puritans, John Owen (1616-1683) was a profound and thought provoking pastor-theologian. His writings continue to be widely read and greatly appreciated to this day.

”Both theologically rich and readable, this short book covers a lot of ground. In eleven brief chapters the glories of an unchangeable God, and His unchangeable word are put forth for the encouragement, assurance and joy of the follower of Christ. For any who are unclear about the doctrine of the Christian’s perseverance, this work is a great introduction that will bring clarity and cultivate worship.“Reuben Hunter(Pastor, Trinity West Church, London)
