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.
