If you want more scripture and less philosophy then you see all the scripture where God chooses and predestines. You see all the scripture that tells us man does not seek God, not even one person.
I don't disagree. From a man's vantage point, prior to faith, it looks as though he is seeking God. But if he's honest, he should acknowledge the sovereignty of God through the scriptures.
In fact, scripture portrays all of history as being preordained and intricately designed by God
You see that the term and idea of free will is not spoken in the Bible.
That's not entirely true.
In regard to seeking God, very true. I believe part of the problem is in thinking that belief is a matter of the will, which a wholly philosophical position in almost every camp.
But in regard to a believer's obedience and disobedience, giving, and other issues of action, scripture paints a portrait of men acting on their own accord.
You see that free-will is entirely philosophical and not biblical.
Not entirely true. The common free-will positions stack free will on top of God's sovereignty, whereas their opposition stack them visa versa. Both are error
If a person is not going to start with a presupposition, but instead is going to start with observation of scripture, then that person will observe what Calvin observed regarding salvation.
That's not true, either. Calvin started with two warped presuppositions:
1) that "salvation" in its most basic sense is saved from hell and going to heaven.
2) that works are an integral aspect of being saved from hell.
He brought those from Rome
That is how it worked for me. That is how it worked for a number of people I have met. They started out being told they had freely chosen God by people in their church. Then, as they read the Bible, they kept seeing God choosing and God's predestination. The observation made it clear that in regard to salvation God chose whom to adopt. The Bible was the definitive answer on the subject.
The Church of Christ points to experiential confirmation, too. They believe that since people from all over the world, who never met, saw the same things from the bible, it must be true. Never mind common presuppositions.
That's an erroneous position to hold, and is unsustainable
