Augustinian, Calvin and Arminius don't determine my beliefs. I wasn't raised in a Christian home.
Here is why I don't believe fallen man can choose to follow Christ:
Faith is a gift of God and humans can't manufacture it.
The whole world is wicked (not politically correct!):
1 John 5 KJV
19 And we know that we are of God, and the whole world lieth in wickedness.
1 John 5 NIV
We know that we are children of God, and that the whole world is under the control of the evil one.
The natural man doesn't understand spiritual things and several natural men whom I know not only don't care about the Bible or Christ, but find both the Bible and Christianity distasteful.
1 Corinthians 2
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
Is everyone spiritual?
Romans 3
11 There is none that understandeth, there is none that seeketh after God.
If they have Prevenient Grace, why don't they understand? Why is everyone under the control of the devil if they have this grace?
In Acts 26 Paul is sent to deliver the Gentiles from the power of Satan:
17 Delivering thee from the people, and
from the Gentiles, unto whom now I send thee,
18 To open their eyes,
and to turn
them from darkness to light, and
from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.
2 Timothy 2
25 In meekness instructing those that oppose themselves;
if God peradventure will give them repentance to the acknowledging of the truth;
Those are my reasons.
