Hebrews 4 conflates belief and faith in the translation you chose to post, but they are delineated in other Scripture--as well as many other translations of
Hebrews 4, which do not have the word "belief" in them--clarifying that the "belief" there is meant "faith," and not knowledge. You might have your lawyers check it out, and get back to me

and i see that this is pointless, but the only comment i made about the OP is "good one," and i still have no idea what you mean about fruit here, sorry.
