A few weeks ago I purchased John Piper's "Desiring God". I have to say that I have found this to be one of the most spiritually provocative books that I have waded through in a long time. I am captivated by the third chapter on worship. It is like taking a drink from a firehose. "All of the works of God culminate in the praises of His redeemed people. The climax of His happiness is the delight He takes in the echoes of His excellence in the praises of the saints. This praise is the consummation of our own joy in God. Therefore, God's pursuit of praise from us and our pursuit of pleasure in Him are the same pursuit. This is the great gospel!" John Piper Desiring God
