You may find this an interesting question: I was just put in charge of Adult Religious Exploration (Education) at the Unitarian Universalist congregation to which I belong. We are revamping the educational offerings for adults. I want to have a “Mysteries of the Bible” class that meets for a few weeks – any ideas where to start? Bear in mind this group consists of people of varying religious persuasions. My minister is an atheist but studied at a Christian seminary (I come out of an Episcopal background). In fact, it is my minister who says it is important to learn about the bible since it is important in our culture. She did mention your name, by the way, as a New Testament scholar.
Welcome kerose98!
Another source you might find useful is the series of lectures on the controversies in early Christian history available from The Great Courses. On the member landing page at the very top there is a link to The Great Courses. Click on it and you will find all of Prof. Erhman’s recordings. Click on The Greatest Controversies of Early Christian History and it opens with a two paragraph description and a list of the 24 lectures’ topics. Mouse over or click on each topic title for a short description of the content. The just under the two descriptive paragraphs is a link to “read more”. Follow that to a much more comprehensive description of the lecture series. Included with the purchase is a 166 page course guide. I had to click on the Q&A tab to find that out. It is a bit expensive, but includes lots of material which I am guessing you would find helpful.
I have had an audiobook copy of this series which includes just the audio for about $15, but it think I will go ahead and get the full package as it saves taking notes and I tend to listen as I fall asleep.
I am not exactly sure what you are thinking of as “mysteries of the Bible” so just a guess on my part.
if you are a new member, you may not realize that Prof. Erhman seldom responds to comments in the Member Forum. Mostly we just engage with other members. I think he does not have time to do both the frequent posts and responses to comments on his posts and go through the Forum as well. Good luck with your endeavor!

Kerose98, Genesis 6:1, 2 & 4 is a mystery. Cain’s mark to prevent others hurting him when there were no others, the ark with two of each kind of animal, the star that lead the wise men to Jesus but no one else seemed to notice might qualify. Good luck getting together your Mysteries of the Bible class.
