In this I mean that, hypothetically, I could see the material aspects of our selves and the world in which we find ourselves as sufficiently influential as to determine some or all of our actions. I am willing to see this as being the way that the God has established the world (or that this is the way it is always set up). In this, I am suggesting that the material world may be designed to bring people to a point wherein they have to make a decision regarding their interaction with God.
I am saying that it is possible to be a compatibilist if you allow people this one act of free will: whether or not they will submit to the will of God. That act, in similitude of Christ’s act of submission, may be our one true use of free will.
