I am so appreciative of your question, EmmyLouWho! And Charsan's answer is good too. Here's my thought on it, for whatever benefit it might be for you.
The Scriptures are a kind of testimony about how things started, how God interacted with the people He created, what He put into place to help them figure out how to live in a way that works, and what happened when they didn't. If you can put together the prophets with the events of the roughly 300 years that Israel was a nation, you can see that all those woe-to-you prophecies were because the people were so corrupted in their thinking that they were sacrificing their own children thinking that this one living and loving God wanted them to do this. (If you look in the early books of the law, you see that God warned them long before that they would end up at this awful point if they didn't take care, but they overall didn't listen.) Fast forward several silent hundreds of years and we get another picture of that same God, Jesus who fleshed out the example of how God wanted us to live. I can't imagine it was easy living without sin - just think how hard it is for some people simply to avoid sweets when they are diabetic! And then He took on all the punishment for what people have done to themselves, to each other, and towards God. This is a big deal.
So why do we have so many debates? I think several things play into it. People only want to follow God just so far, so we all have to twist the words a bit to be comfortable where we think we need to be. Then we seem to want to try to make everyone else be in that same place. And along the same lines, people are still trying to be "better than" each other rather than better than they were and staying busy working on the beam in their own eyes to better see the measure of Christ in our own lives. The Pharisees/Sadduccees/other sects/scholars/philosophers and the religious hypocrites (play actors) didn't disappear over time. They were there in the scriptures and they are still with us. Some of them ARE us. They went their own way and tried to pull a following after themselves. And we do have 2 thousand years of cumulative error in church history with each break-off from the last "orthodoxy" thinking they have arrived and the rest are all wrong - another case of thinking we each have arrived and can check off all the boxes for God's acceptance while we despise the others for not agreeing with us. All that...and we still have the promise of a certain end of this present age.
The forum here has the unique opportunities to share additional wisdom or to perpetuate long held myths. But then, Jesus told us God's kingdom (those of us who want to live under God's rule?) would be like a field with both wheat and tares - and it's not up to us to do the weeding. He did say what would happen to both in the end, and that's probably the vital lesson. Be wheat. Work on your own chaff.
Conclusion: this walk is up to you. You've got the book in your hand if you want to study it. God is more than willing to give you all the help you need through His Holy Spirit so that you can see where others have wisdom and where they don't. Study and keep studying. Walk in it - and keep walking in it. God is interested in you and your life - and in your perseverance to the end.
OK, jumping off the soapbox now, lol - what a dynamic question. I hope the best for you!
