I have to believe that at least the majority of religious people don't think that believing things without question is necessary in God's eyes. It just seems so ludicrous.
Without question? Of course, everyone, even the most earnest of believers [if they are also honest] will have and admit to having questions. What is needed that too many believing Christians do not have is the ability to hear what God is saying to their hearts.
Unbelievers hear little from God and often if not usually reject and/or misunderstand what they do hear. For them [the unbelievers] while they have time and opportunity that may be OK until time runs out for them.
For believers, if they really are believers, they must recognize the Voice of God. This is their Way to Him. Abraham and Isaac and Jacob had no written scripture, but they according the scriptures [which you don't want us to use here] they did hear from God. They heard His voice, whatever that meant to them. God will be understood by anyone who approaches Him properly.
So does He care? Why would He bother to speak as He does if He did not?
I hear His voice, but at times I quench the Spirit, His Spirit, and I get into trouble with Him. Does He care? If He did not I would not received additional chances.
Give God the glory!
