And since then, not an audible word to anyone?
That’s not consistent, or logical.
How familiar are you with the Bible? God is as consistent and logical as it gets. I highly encourage you to read and muse upon the entire Bible and perhaps it will click for you. Talking with a friend or other person with access to others who can help explain questions would also be useful.
I used to be at least as scornful as you seem to be until I actually heard the Good News of the New Covenant and became saved. Until then, most of the Bible made no sense to me. I used to make my own "rational" conclusions without so much as exploring the subject, reading appropriate passages or talking to someone with more long-term involvement in Scripture. All my questions/objections were answered with a contextual reading/discussion of them.
