Let's tease this out a bit. Do committed Christians vote for Huckabee and casual Christians do otherwise? Speak plain.
Casual Christians believe in Christ, but are uncomfortable with public displays of faith. They go to church every once in a while, particularly at Christmas and Easter. They don’t read the Bible by choice, and they certainly don’t believe it is literally true. If asked if they are a member of particular denomination, they say yes, but they only follow the doctrines they like and justify it.
Committed Christians not only have faith, but they try to live faith. They believe that living their faith is right even when they fall short sometimes. They go to church as often as humanly possible because they love going. They belong to a denomination (confession) and follow the doctrine or feel really guilty. They believe that prayer works. Most of all, they are comfortable praising God in public and aren’t upset when someone else does.
Commited Christians creep Casual Christians out. They think that they are either faking it, or they are stupid hillbillies. They fear that the Committed Christians are nutty enough to actually let faith affect politics.
