The finished works of Christ is the action received by gospel faith and upon which faith rests solely as its only hope of salvation. The faith which receives and rests upon the gospel for salvation is the same faith that then responds in love through works or "unto good works."
You simply cannot distinguish saving faith which embraces and rests upon what Christ does for you from sanctifying faith which is what you do for Christ. The former is the cause while the latter is the consequence but both are found together in every true child of God.
If one is to believe in your beliefs, Biblicist, then one would have to say that unsaved people never do anything right ever. You would have to believe that no atheist or anyone other than a Christian ever did anything right ever.
