Could you be convicted for being a christian?

What should you be doing to truly be classifid as a Christian? I heard a sermon once on if you were arrested for being a christian could you be convicted based on the evidence of your life. By what standard would we judge ourselves? I think that at times we sort of make up our own rules of right and wrong. But for a christian do we make up our own pattern of what it really means to be a christian? Things like all of the political languange people use at church functions to me is a sign that we are missing the mark. Like this last Sunday a preacher that I had never met before told me that the President gets a scripture message from one of the big name christian preachers. He gave me a name but can't remember what it was. I thought that was pretty neat but then he said that he also gets the same thing based on the Koran. Then for 15 minutes he kept on about how bad this was for a christian nation to have a leader that would take anything from the Koran. I spent ten minutes or less of looking on the www and I found that this is another rumor that has been going on since before he was elected President that is not true. Is it only a lie if we do not think is an untruth? Does the Bible not say that all liars shall have their place in the lake of fire? Maybe it is a one time thing where we confess our sins in prayer (repent) and then we just live life trying to do the best we can? One thing I want to make clear. This show is not about what is the process of having our sins taken away. We are looking for what happens after that process that makes you different then those who do not claim to be a christian. What is your responsibility to God to be judged a christian after your commitment or repentance is made to God. Look forward as always your thoughts on this topic.
