ChristianAudio.com is offering the classic
The Pursuit of God by A. W. Tozer
for a free download for the month of July.
Note: ChristianAudio offers many types of audio so beware of whom you listen to. I don’t recommend just listening to a new author unless you have checked them out. However, they do offer some very good audios such as this one at times. Just beware. Use Biblical discernment.
