I don't think I've ever just forwarded something like this, but I just listened to this sermon and I think it really bears listening too. I recently had two brief discussions with friends about whether or not there is a spiritual world. What do you believe? What you believe affects how you live and pray.
Listen to this while you make dinner tomorrow, or while you're getting ready for bed, or whenever it is you have 45 minutes. And if you don't have time, at least include Ephesians 6:10-20 in your thoughtful reading of the bible this week.
