This one here proves my point! God uses men, things, His creation foremost, and the Spirit. I'm not disputing that this is all a work of God. For even sound reasoning is a work of God.
Don't forget verse 64:
64 But there are some of you who do not believe.” For Jesus knew from the beginning who they were who did not believe, and who would betray Him.
This is the point I'm trying to make, that God knows our hearts and who would and would not choose him, thus He chooses us according to His pre-knowledge of our free-will, not out of a ambiguous line up.
I didn't think this tread was about predestination. I had up to my head with this debate. I don't wish to partake in it any longer. I thought this was about how reason can bring about faith. I know reason by itself can't, but sound reason and the power of the Holy Spirit can, because God can use anything he wants.
