Titus 1:15-16

Darby Translation

¹⁵ All things [are] pure to the pure; but to the defiled and unbelieving nothing [is] pure; but both their mind and their conscience are defiled.

¹⁶ They profess to know God, but in works deny [him], being abominable, and disobedient, and found worthless as to every good work.
