For years I have been bothered by the footnote of James 4:17

"A concluding word to all the charges in the preceding verses. It says that if the recipients of this Epistle are helped by James's writing and yet will not do as he wrote, to them it is sin."

The author of the footnotes implies James 4:17 "Therefore to him who knows to do good and does not do it, to him it is sin." is conditional and optional.
