Faith

From the King James Bible, the pure Cambridge edition.
"So then faith cometh by hearing, and hearing by the word of God."

If you do not have the pure words of God, today in English that is the KJB the PCE, you will never be saved. Most people have satanic counterfeits that have lies in it. Mark 1:2 is a lie if it says words to the effect of As it is written in Isiah the prophet, when in truth it's in Malachi; Or in Hebrews 3:16 all who Moses lead out of Egypt rebelled, when it truth Joshua and Caleb were faithful. And many other places - perversion of truth takes place. But people do not care.

"And whosoever was not found written in the book of life was cast into the lake of fire."
