The idea for this site came after I had done a teaching series at my church by the same title. If you enjoy listening to podcasts, you can listen to any of the ten original messages here. Or you can subscribe to my weekly podcast with this feed: http://feeds.feedburner.com/GrowDeeper.
If you use iTunes, simply copy the link above, in iTunes click on Advanced. Click on Subscribe to a Podcast. Paste this feed url (from above) into the box. Click OK. Open up the podcast and decide which episodes to download. The Zombie series is from the beginning of 2012.
I hope these resources are a help to you. Please let me know.
