The Difference Between a Christian and non-Christian

What is a distinguishing mark of a believer? At our 2009 Pastors Conference Mark Dever gave us a helpful and memorable word:

The difference between a Christian and non-Christian: When a non-Christian is convicted of sin, he sides with his sin. When a Christian is convicted of sin, he sides with God, against himself."

For further thought, see John Piper's 1992 article "What Is a Christian?"
