I have to share this because Phil Johnson nailed it. He delivered a sermon on how pastors should shepherd their flocks during an election year. It is wonderful. Because he is a brilliant, clear thinking communicator he is easy to listen to, because he is a solid believer what he has to say is valuable. He has succinctly put what I have been trying to say regarding the Obama/Wright controversy. His first point is preaching not lobbying is how we make the truth known. You'll find the link here. He is teaching a group of pastors. If you're not a pastor, don't let that keep you from listening. It is valuable for all. By the way, you can find more of Phil's mp3's to download here and his Pyromaniacs blog here.
I will warn you, you will be challenged and stretched, but you'll be blessed.
