The Bible Project is one of the most consistently helpful resources out there. Their core belief:
"From page one to the final word, we believe the Bible is a unified story that leads to Jesus. This diverse collection of ancient books overflows with wisdom for our modern world. As we let the biblical story speak for itself, we believe the message of Jesus will transform individuals and entire communities."
I'd like to recommend 4 ways you might choose to utilize the resources here, depending on where you are at.
1. Watch the Videos - there have a LOT of short videos on various themes throughout Scripture.
2. Check out the Podcast. This comes out once a week and his about an hour long. In it they take a deeper, but accessible, walk through the larger themes of the Bible. The material from the podcast gets distilled into the short videos I just mentioned.
3. Read through the Bible. There is a Bible reading plan with the YouVersion app that has video intros from the Bible Project along with daily readings.
4. To go Class! They are developing an online classroom function that goes even deeper. This is a great way to really dive in and might be for you especially if you are preparing for teaching ministries or want deeper ongoing education.
I know that I learn something every time I engage with the material from The Bible Project and I think you will as well!
