Finding a true Christian here is like finding a needle in a hay stack.  They profess to know Christ, but are proud to publicly proclaim their sins of fornication, drunkenness, cheating, lying, etc.

Titus 1:16 They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate. {reprobate: or, void of judgment}
