The Bible says there is dead faith:
(New Testament | James 2:14 - 20)
14 What doth it profit, my brethren, though a man say he hath faith, and have not works?
can faith save him?
15 If a brother or sister be naked, and destitute of daily food,
16 And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body;
what doth it profit?[/QUOTE

Faith doesn't save us --- Jesus does!
1And you hath he quickened, who were dead in trespasses and sins; 2Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: 3Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. 4But God, who is rich in mercy, for his great love wherewith he loved us, 5Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved); 6And hath raised us up together, and made us sit together in heavenly places in Christ Jesus: 7That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus. 8For by grace are ye saved through faith;
and that not of yourselves: it is the gift of God: 9Not of works, lest any man should boast.
9Not of works, lest any man should boast. 10For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
The Bible speaks of living faith in Christ. Dead faith in false religions is not a topic.
8 For by grace are ye saved through faith (in His blood); and that not of
yourselves: it is the gift of God: 9 Not of works, lest any man should boast.
If you believe the Bible (all of it) then you will know there is dead faith. You can't be saved by dead faith.
If someone says he has faith, but his life isn't transformed, we can't believe he has genuine faith. Salvation is by faith alone. Genuine faith produces good works.
Faith in a pet dog doesn't give eternal life. Faith in a false Christ doesn't grant eternal life.
