Do you question that this faith being demonstrated by our Amazonian Forest dweller from the 1200's is really faith? (Fun fact: Amazon Prime was only $29.99 back then). He has the faith described by the author of Hebrews...
3By faith we understand that the universe was formed at God’s command, so that what is seen was not made out of what was visible. Hebrews 11:3
6And without faith it is impossible to please God, because anyone who approaches Him must believe that He exists and that He rewards those who earnestly seek Him. Hebrews 11:6
Salvific faith requires facts to be believed in order to be saved. I believe (have faith) that if I drop a pencil it will fall. This is faith, but it is not Faith that Saves.
Similarly, Heb. 11:3 is about faith, but knowledge that the universe was formed by God is not "saving faith"; if it was then the Muslims would be saved (maybe you believe they are). You need to read verses that speak of: Faith that leads to salvation and what the contents of that faith are.
Same analysis of Heb 11:6 though believing God exists is a part of "Saving Faith" but not all of it. Again, one must read ALL of the verses that define what SAVING FAITH is (not what Faith is) and what SAVING FAITH cannot be. John 3:18 says what SAVING FAITH is not ... I says FAITH DEPENDS ON KNOWLEDGE OF CHRIST and therefore one knows the Amazonian could not have been saved.
Aside: I you ask 10 knowledgeable Christians the exact formula for what one must do to be saved you will probably get 9 different (not totally different) answers. You're a good example.
