How does one apply scientific methods to a being that is supernatural (outside of the natural realm). Science can only be applied to the things it can test and a supernatural being does not fall into that category. You test the natural with science that was developed within the natural and the supernatural by faith. This is why atheist and theist disagree at a basic level, the basic level for most atheist is science and the natural world and for theist it is faith in a supernatural being. For me of course the God of the Bible is whom I place my faith in. We are on opposite sides of a wall and that is where our trust will stay unless someone or thing destroys that trust, this wall most likely will not be breached by words alone but can be by anothers actions. So life goes on and we trust in what we know is right for ourselves.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
