Faith's definition:unquestioning belief
Work's definition:effort of doing or making
Faith is not salvation,salvation is only obtainable through Jesus Christ,when an individual out of faith asks God to save their soul and accept Jesus as saviour,is salvation"Given" to the individual as well as "Given" the holy spirit to accept or reject,or accept then reject(which is why blaspheming the holy spirit is the "only" "unforgivable" sin for one must believe to accept and then reject the holy spirit in order to blaspheme the holy spirit)
Salvation is "Given" through Jesus by God,Earning Salvation is not possible once one accepts the grace of Jesus Christ,for his grace makes "salvation" possible "without works" one can only choose one,the Law for salvation or Jesus's grace,there is no other choice but these two,True God would want people to "work"'by spreading his word,but once accepting Jesus's grace "salvation" is already obtained,thereby "works" are no longer apart of one's "salvation" but they are still apart of one's walk in life with God still,this is why in James it speaks of "faith" not salvation being dead without works,because "works of faith" show God that you are more than "talk" concerning one's appreciation for "salvation" that was "Given" them but also that they will "hearken" when God has a task for them to do for him.
