Unto 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. They profess that they know God; but in works they deny Him, being abominable, and disobedient, and unto every good work reprobate.”  Titus 1:15-16  (KJB)
