I am somewhat new to studying apologetics. However, I am trying to understand presuppositional apologetics. I have read some John Frame books, such Apologetics to the Glory of God, DKG, parts of DG. I have also read some of his online articles. I have seen him make the claim that God's nature is the ultimate basis of logic. My question is simply, is this right, and if so, how can you prove philosophically and Biblically? I agree that the laws of logic, science, and morality are unintelligible in other worldviews, and that when other worldviews use the laws, they are in fact borrowing from the Christian worldview. However, when I try to prove that the laws of logic and science presuppose God, I have a hard time doing that. How do I KNOW that the laws of logic and science presuppose God? I am aware that you can give philosophical arguments for this all day, but can it be proven with Scripture? Any help in understanding these issues would be greatly appreciated.
