What a small price to pay

What does it mean to you to be a Christian?  When you hear someone say they’re a “Christian,” what does that actually mean?  Does it mean they attend a church on a regular basis?  Does it mean they grew up in a Christian family and believe in God?  Does it mean they once prayed a “sinner’s prayer” — perhaps as a child at summer camp?  I ask these things because when people tell me they’re a “Christian,” I have to wonder, because “being a Christian” doesn’t seem to mean what it used to mean.
