There is no worse screen to block out the Spirit than confidence in our own intelligence.
Yet, that is exactly what you are proposing by naming faith as something anthropomorphically derived. If faith is a gift of God, the the Holy Spirit is the one doing the gifting. If faith is something that we generate within ourselves that allows us to come to God, then we are indeed hindering or counterfeiting the work of the Holy Spirit.
With regard to Eph. 2:9: Many persons restrict the word gift to faith alone. But Paul is only repeating the former statement. His means, not that faith is the gift of God, but that salvation is given to us by God.
I am not doing that. I realize that SALVATION is of God, and that faith is one part of what we call salvation.
Additionally, I cannot see how arguing as you have here is actually helping your cause. But you did just admit to a Calvinistic principle, that the components OF salvation, faith being one, ARE from God and not from man.
Of course, you will come back with your standard caveat, that if I (we) just understood Classical Arminianism, we would grasp the fact that God is yet supreme in salvation, His grace going forward before any actions of man, &c. The problem is, we DO know it, and we watch you argue it often when it is convenient to your platform. But you always end up defaulting to an anthropologically-centrific position eventually. You have to because of the final clause build into most of the 5 Articles that stipulates that God only acts as He knows man to act first -- the fatal flaw in the Arminian position.
Human will is not "free" in a libertarian sense, it is bounded by God's decrees. We also do not have the "choice" to "choose God" for we have no ability as slaves to sin, cursed to death, dead in our sin and trespasses, individuals to choose anything save for more sin, because even our "good works" as as "filthy rags" to an utterly holy and righteous God.
