In her book Because He Loves: How Christ Transforms Our Daily Life, author Elyse Fitzpatrick writes:

Just in case you're unaware, identity theft occurs when someone steals your name and other personal information for fraudulent use. Most of us are dismayed by this new cyber-age crime, and we wouldn't assume that the theft of another person's identity is acceptable behavior. The surprising reality, however, is that Christian's are, by definition, people who have someone else's identity. They're called "Christians" because they've taken the identity of someone else: the Christ. Not only have you been given an identity that you weren't born with or that you didn't earn the right to use, but you're invited to empty the checking account and use all the benefits this identity brings! This is so much better than identity theft—it's an identity gift!
