Hey guys! Just wanted to share a favorite sermon podcast of mine- Mars Hill Church. The style is modern, but the theology is sound. Some consider it too old-fasioned, but I believe it's very Biblical. They are also currently ranked #3 on iTunes podcasts under Religion and Spirituality, so congratulations! :)
You can check them out there, or get their current sermon series at www.marshillchurch.org
... I would consider the current series for high school students and up (that means not you Emily!) but they also have all their old series up as well.
