I did not avoid your questions. I answered them, twice.
Regarding free-will, I thought your statement rhetorical. Were you serious in thinking that any of us have not used our free-will to step forward in faith? Everybody has a free-will, and it goes without saying that we are all using it, all the time.
Likewise, when we obey the Holy Spirit, we use our free will. And Peacefulbeliever answered your question, too. She stated correctly that we are in control of our body while we pray "in the spirit".
You say you study your bible, well these things are written about by Paul in 1 Cor 14:15 "I pray with my mind and I pray with my spirit, too."
It gets silly to say, "I'm going to exercise my free will now and drink this glass of water. Oh, I'm going to exercise my free will now and read the bible. I'm now going to exercise my free will and pray to Christ."
So your "question" seemed not serious, to me. But I'm not trying to offend you at all.
When I asked you to elaborate on your born again experience, you failed to speak of your encounter with Jesus. Did you meet Jesus? Or... did you have a spiritual "eye opening" experience?
I'm only asking because it may be that you think are a Christian, but may not be. Allow me to pursue the inquiry.
A Christian is a new species - born of the Spirit. A Christian is not a person who has taken their energies which use to be used in one direction, and now has turned them into a different, better, religious direction. Not at all.
The whole bible teaches that only a new type of man can come into the kingdom, one who is born of the Spirit. Nicodemus asked about this, and Jesus taught such.
And now, when you become a born again of the Spirit creature, you continue in the same way you began... by the Spirit!
It is NOT a taking of your powers (free will, energy, will power, thinking, all your soul power) and now applying that to "a good direction". NO!
And so, this helps to explain how the countless millions who have answered an "altar call", or responded to a psychological persuasion, or philosophized into christianity , really is not the thing. Perhaps God uses these things, but the real deal is if God calls a person and gives them miracle birth.
Not a single true christian has ever chosen God. God does all the choosing and calling. It is ever so.
