located in the upper right hand corner of the sermon outline.

To save the sermon for listening offline, right click "Listen to the sermon,"
select "save target as," give the sermon a filename, and

The downloaded sermon can then be played offline anytime you want.

If a particular sermon outline does not have the link "Listen to the sermon"
