Titus 1:15–16
15 jTo the pure, all things are pure, but to the defiled and kunbelieving, nothing is pure; but both ltheir minds and their consciences are defiled. 16 mThey profess to know God, but they ndeny him by their works. They are detestable, disobedient, ounfit for any good work.
James 2:19
19 tYou believe that God is one; you do well. Even uthe demons believe—and shudder!
Ephesians 2:8–10
8 For zby grace you have been saved athrough faith. And this is bnot your own doing; cit is the gift of God, 9 dnot a result of works, eso that no one may boast. 10 For fwe are his workmanship, gcreated in Christ Jesus hfor good works, iwhich God prepared beforehand, jthat we should walk in them.
