For by Grace I have been saved (past tense) through the means of faith, And not of anything I did on my own (work), it (Salvation) was a gift of God. It was not by the means of works that I was saved, Otherwise, I could take credit for Saving myself.
I do not see where you get that term that faith is not of my own, I do not see it in the passage.
Faith is not a work.. So we can not boast of having faith, unless our faith is in our own works (the Pharisees we're proud, because they had faith their works made them acceptable to God. I can not boast, because my faith is solely on the work of God, and not anything I did of myself)
How do you come to the conclusion that "and that not of yourself" only applies to the grace, but not to the faith?
If this is annoying to you, we can drop it.
