This is a great product. It is fully working as of last week for me (I use Microsoft not apple not sure if that is the problem). My wife and I love to sing 2 worship songs, have a personal devotion for 30 minutes then follow up with this on the section we went over. The language is simple but there is depth to it. I have preordered the rest of your commentaries as a result. Thank you for your hard work Dr. Runge!
