The topic was faith, which is salvific. If the faith is what saves then only God can give it, free will notwithstanding. And, by the same token, if lack of faith is equal to being lost then it is also God's doing, lest humans have a role in salvation/perdition of man.

[Cronos]

you're right, Faith is a grace. When St. Peter confessed that Jesus is the Christ, the Son of the living God, Jesus declared to him that this revelation did not come "from flesh and blood", but from "my Father who is in heaven"

Faith is a gift of God, a supernatural virtue infused by him. "Before this faith can be exercised, man must have the grace of God to move and assist him; he must have the interior helps of the Holy Spirit, who moves the heart and converts it to God, who opens the eyes of the mind and 'makes it easy for all to accept and believe the truth.'"

but, in faith, the human intellect and will co-operate with divine grace. As Thomas Aquinas wrote: "Believing is an act of the intellect assenting to the divine truth by command of the will moved by God through grace."
