Here at Thinking Matters we love free stuff, so whenever something is free and of a high quality, we go for it!
The free audiobook this month is Delighting in God by A. W. Tozer; you can find it at christianaudio.com/free/. Usually it will cost you $15 (US), however, for one month only, it is free of charge.
Here is the summary from Christianaudio.com
Delighting in God is the message Tozer intended to be the follow-up to The Knowledge of the Holy. He demonstrates how the attributes of God–those things God has revealed about himself–are a way to understand the Christian life of worship and service. We are here to serve and adore him, but we can only fulfill that role by acknowledging who he is, which is the essence of the Christian life and the source of all our fulfillment, joy, and comfort.
