Austin you claim to be the scripture purist so why do you add your own view when your commenting on a text? You claim that man has to be given faith so I checked for that in Romans 3. This is what I found.
through faith vs 22, through faith vs 25, justifier of the one who has faith in Jesus. vs 26, by the law of faith. vs 27, justified by faith apart from the deeds of the law vs 28, justify the circumcised by faith and the uncircumcised through faith vs 30, through faith vs 31.
Well I figured that you must have some justification for that claim so I did a search for "faith + gift, or "faith + given" in the NT and did not see where faith has to be given to someone. So it would seem that you are bring your view into the text.
So it would seem you should have just written. In
Romans 3 Paul lays out the fact that both Jew and Gentile are only justified before God because of the faith they have in Christ Jesus alone. And have left out (been given).
