The word faith in the Bible is also translated as belief.
It tells you in the Bible that even the demons believe (In God) and tremble
believe [that]—
πιστεύουσιν (pisteuousin)
Verb - Present Indicative Active - 3rd Person Plural
Strong's Greek 4100: From pistis; to have faith, i.e. Credit; by implication, to entrust.
but this is not the same as belief that saves.
Belief that saves is different than simple believing these things are real. One can in fact believe or have faith, without having believed unto salvation.
