Comment on Science and Methodological Naturalism by Sean Pitman.
In any case, your quotation of Galatians 3:24-25 seems out of context. The "Law" Paul is speaking of here which functions as a "schoolmaster" is the Ten Commandments which leads us until we find completeness in Christ through faith – at which point the schoolmaster is no longer needed. The same is not true of the natural world which is no longer needed once the Bible is found. That's not true at all. The study of nature and of God's Word shed light on each other. They are both God's revelations of Himself and, as such, the study of both is important to learn and grow in the understanding of the nature and character of God.
Again, while the Bible most certainly gives us a much more detailed picture of God, many attributes of God can be learned through the study of nature alone that cannot be as clearly recognized through the study of the Bible alone… so that even those who never had access to the Bible are "without excuse". This is true despite nature being marred by sin. That is why having access to both the books of nature and the written Word is most ideal. One, without the other, leaves one handicapped, but not completely in the dark regarding the nature and character of God.
Clearly, then, the Bible itself also promotes the idea that God can be recognized as God through the study of the works of His hands – of the empirical evidence found in nature (as does Mrs. White). Sure, the Bible gives a much clearer and more detailed revelation of God and His character, but do not discount the ability of nature to reveal important truths about her Creator for those who are open to taking their first steps toward God. Many scientists have been converted to the Christian Gospel message after first having recognized a Divine Hand behind various features of the universe and the world in which we live. Such steps are often the very first steps that some must take before additional steps can be taken toward a fuller discovery and relationship with God.
Gravity must be caused by an agent acting constantly according to certain laws; but whether this agent be material or immaterial, I have left open to the consideration of my readers.
Yet, even though Newton didn't know "how" gravity worked, no one would argue that he wasn't using scientific reasoning to describe its very predictable effects.
The same is often true in medicine in that it is often the case that it is known that a certain treatment or medication consistently works to produce a particular result, but exactly how this result is achieved is unknown.
That's just the nature of science. Science can detect certain predictable relationships, certain predictable cause and effects, without knowing "how" a suspected cause produced or produces the phenomenal effect.
As far as "methodological naturalism" is concerned, the problem with this concept is that many scientists are arguing that only mindless natural causes should ever even be considered when trying to explain all natural phenomena. This is an obvious inconsistency that has nothing to do with explaining exactly "how" an intelligent agent produced a particular phenomena that would seem to demand intelligent input.
For example, I might not know how to make a chocolate cake myself, but I can still know that it required intelligent design when I see one. The same thing is true of highly symmetrical granite cubes or a radio signal tagged with the first 50 terms of the Fibonacci series or a Shakespearean sonnet or the information in the DNA sequence of a bacterium beyond the lowest levels of functional complexity.
You talk about this god of love and everything else. But somehow if you don't believe in him, you don't get any of the benefits, so you have to believe. And then if you do anything wrong, you're going to be judged for it. I don't want to be judged by god; that's the bottom line (podcast: 58:01).
