I don't find BushOklahoma being a fan of a conservative Baptist surprising at all...
Yeah he's conservative (theologically), and a Baptist, but Piper is a little more intellectual and theological than I would have imagined BushOK would be into; he's essentially a Charismatic Presbyterian who baptizes adults. He's hardly the typical SBC megachurch guy (he's not even SBC)...
One thing you should know about me, while I am a Southern Baptist, I am a Christian first. I can worship with anybody so long as they believe that Jesus died on the cross for our sins and that He rose again and lives today. The other items are just "stuff". Plus, I am a little more liberal than a lot of Southern Baptists. For instance, I am in favor of civil unions and not 100% opposed to gay marriage. Plus, I voted for President Obama and actually respect Nancy Pelosi which is almost a no-no in Southern Baptist circles, especially in red-state Oklahoma. My theology is also just a little different. I believe in the election of the saints as described in Romans 8. I am quasi-Calvinist. I am not fully Calvinist (complete predestination) and I am not fully Armenianist (complete free-will). I am what you would call a "graceman" where I have tendencies on both sides and believe everything that is done in our lives is a reflection of grace, and I do subscribe to the "TULIP" doctrine, even though it's not 100% Biblical. That's kind of where John Piper comes in. I agree with his theology most of the time. At my church, my pastor, who is also my cousin, takes everything in the Bible at face value, and believes whatever it says and believes it happened exactly how it was written. He likes to go back to the original Hebrew and Greek manuscripts to get the true meaning of Scripture.
