Does Paul teach faith plus nothing or faith plus works for salvation?
Paul teaches salvation is by faith plus nothing, not faith plus works. Works follow after salvation as a natural result of faith, so no one can boast or claim they did something for salvation. The law of faith excludes works; believers rest totally on what has been done on their behalf.
Les explains that Paul repeats this truth often: the law of faith, not the law of works, excludes boasting. James says faith without works is dead, but Les does not get into that controversy; he distinguishes Paul's teaching that it is faith plus nothing until we are saved. After salvation, works naturally follow as a result of faith. This means no one can come back and say, 'I did this for my salvation.' Instead, we rest totally on what has been done on our behalf.
