Since this is the case I wanted to share with you a link that came across my twitter feed early this morning - Advance 2011 media -
This is a media page for the teachings given at Advance 2011, a conference that happened in North Carolina. You can download each of these for free.
I would encourage you, as I tweeted this morning, to use these to redeem your commute this week. I haven't listened to any of these yet and will be doing this myself.
Listen to 1-2 of these this week and watch how God will transform our hearts for our communities and cities.
