What Is a Christian?

Recently, I've been reading Evangelicalism Divided by Iain Murray, and it's got me thinking. In it, Murray plots the 2 paths that Evangelicalism has taken in the past 50 years. A path toward biblical Christianity or a path toward liberalism. One of the many forks in the road for these 2 paths was how the following question was answered: "What is a Christian?"

So that's the question I'm posing to you.  What is a Christian?  What makes someone a Christian?  I think this is an important question for all of us to think through, and the answer has massive implications that we might not realize.  So here's what we're gonna do.

You have one week to leave a comment on this post answering the question, "What is a Christian?"  I'll try to interact with you as you post your answers.  One rule though...  I want people to feel free to answer this question without the fear of ridicule or condemnation.  Therefore, if you leave a comment that is derogatory towards anyone's answer, it will be deleted immediately.  Let's be gracious to others just as Jesus has been gracious to us.

At the end of one week's time, I'll follow-up with a post that summarizes your answers, show some of the implications of some of those answers, and then share how the answer to this question caused division between Evangelicalism in the past 50 years. So have it.
