Grace alone means that woth faith and good works are the result of Divine Grace and nothing else. Eph 2 says the same thing: that works do not produce grace. It does not say that works do not produce faith.
What??? :) Here is the passage we know so well:
Eph 2:8-9 : 8 For it is by grace you have been saved, through faith — and this not from yourselves, it is the gift of God— 9 not by works, so that no one can boast.
Is your argument, based on this, REALLY that works do not produce grace BUT works DO produce faith??? By the standards of your interpretation, I can claim the truth that God saves every third person with a "W" in his name. My evidence? The Bible says nothing, EXPLICITLY, against it. :)
