Introduction by Daniel Montgomery. As he expounds this wonderful psalm Dr. Martyn Lloyd Jones sees a great choir, drawn from the four corners of the earth, united in praising God. Using the Psalmist's vivid word-pictures he underlines the sheer grace of God who rescues sinners from the wilderness, frees them from prison, heals them from dreadful disease and saves them from a terrible storm. Throughout this superb exposition Dr. Martyn Lloyd-Jones show the profound difference between false and true religion. True Christianity always, and inevitably, leads to grateful and heart-felt praising of God 'for his goodness and for his wonderful works to the children of men.'
