Sound in the Faith

Titus 1:10-16, KJV

10For there are many unruly and vain talkers and deceivers, specially they of the circumcision:
11Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake.
12One of themselves, even a prophet of their own, said, the Cretians are alway liars, evil beasts, slow bellies.
13This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;
14Not giving heed to Jewish fables, and commandments of men, that turn from the truth.
15Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
16They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.

The same still holds true today. Be careful not to become one of them. (Titus 1:16)
