If a question is asked in good faith and reverence before God, God always gladly answers. Never in the Bible has God ever answered "because I say so." Unfortunately, many fundamentalist Christians take that approach. This is also resulting in, or caused by, the bad parenting tactic: Because I say so, against smart, inquisitive children.
I am reminded of Janet Mefferd's talk show, which always in every episode, intro with a preacher (Dr. W. A. Criswell, I think, in his Acts 20:19-21 1995-11-01 Sermon titled Old Time Religion @10:15) yelling: "But if the Word of God says it, I believe it!" Now that I found this preacher and sermon, the context of that phrase, though seeming meant as a joke, is of highly fundamentalist's narrow minded view: Two boys glued the preacher's Bible pages together so when he preached "Noah was married to his wife...and she was fifteen cubits broad" unknowingly that his pages were glued, the pastor continued "this is the first time I saw it in the Word of God. But if the Word of God says it, I believe it!" It's no different than Roman Catholicism: "If the Church says it, I believe it."
So it's not new, this anti-intellectual path.
This had been a series of encounters I've had with folks like Alex Tseng ("LGBT/"gay marriage is sinful because the Bible says so"), Pastor Chris of GCC ("God says so", "Reason cannot save you, only Faith can"), on top of the preachers such as from the intro of every Janet Mefferd episode. I am not critiquing them for Sola Scriptura, but when it becomes Solo Scriptura or the tendency to be so, that's when the problem comes which I think all of them committed. It is usually a sort of narrow-mindedness, the inability to understand who they are conversing with, the incompetence of having a better answer, the pride of being self-righteous.
It must be noted that before they answer "Because God says so", the question already assumed God says so. So it is a redundant answer "because God says so," as if they need such reminder or to remind others themselves. But of course, they would all say: I am not against reason, I'm not against LGBT people, I have a lot of gay friends, I'm not perfect, etc. Textbook means of covering their own "humble" behinds.
So after all this, I dare to challenge even their theologians, that though we can always start with God says so, or the Bible says so, saying BECAUSE God/the Bible says so, is actually unbiblical, to any question asked in good faith and reverence.
Why forbid the eating of the fruit? Because God says so. That is an unbiblical response.
In fact, the strongest lesson on this topic in the Bible is the book of Job. When God rebuked Job in the end, it is exactly because Job did not, in all his fear of God and righteousness, ask the questions that God asked. Questions God demands man to seek answers to, so that man could fulfil the responsibility and the purpose of MAN. Rather than just being complacent with "because God said so." Mankind MUST ask WHY. Even Jesus called out the servant with the least talent (Matthew 25:25-30): Thou wicked and slothful servant...take therefore the talent from him...from him that hath not shall be taken away even that which he hath...cast ye the unprofitable servant into the outer darkness. Job asked something, but his problem was he did not ask God directly, he did not seek such relationship. He feared it. He feared not the works of righteousness, he feared the relationship with God. He wanted to just stick with "Because God says so, what else did God say, and I'll do." Pastor Chris misunderstood the parable of the talents even further from the truth, that he thought the parable was about being afraid to work. He saw the word "afraid" in verse 25, but he missed the point of "to every man according to his several ability" in verse 15.
To say because the Bible says so, or reason cannot save you but only faith can, is basically advocating superstition, or blind faith. Rob of GCC wanted to give a biblical example in defense: God says He is God. But that's off topic, because it begs the question: What is the question, that you need to answer "Because God says He is God?" The only response to that is in the presuppositional apologetics: How do we know God is God, because He says so. This is a statement of ontological identity, not an explanation of why.
