[Petronski]

So God's grace doesn't save?

I didn't say that.

I will, again, call your attention to the Gospel according to †John:

For God so loved the world, as to give his only begotten Son: that whosoever believeth in him may not perish, but may have life everlasting. For God sent not his Son into the world, to judge the world: but that the world may be saved by him. John 3:16-17

The statement "grace saves; not faith" is necessarily defective, in that it suggests faith is somehow unnecessary

Protestants are fond of saying sola fide, yet "grace saves; not faith" stands that on its ear. Salvation requires God's grace, faith in Christ and works that bring that faith alive (in the fullest sense of "believing in Christ:" doing as He commands).

[Dr. Eckleburg]

Men are saved BY God's grace THROUGH faith in Jesus Christ. I'm assuming your Bible also contains Ephesians 2...

"Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)...

For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:

Not of works, lest any man should boast.

For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them." -- Eph. 2:5,8-10

Paul stressed this fact so earnestly that he repeated the exact verse twice within a span of four verses.
