I love the discussion on this passage.
At the point in time I recognize as my “conversion,” I was faced with a question of trust, but was also keenly aware of the Holy Spirit being present, drawing me towards faith, and ultimately assisting in the choice to believe. Exactly how, I cannot tell. He is indeed like the wind, as Jesus mentions in John 3.
I appreciate the fact that you state it’s not one specific answer…he is a God we cannot contain, nor stuff into a box.
