It really depends upon what your starting point is.
I struggled with this and many other questions. Like you, I found mixed messages from different groups. The Bible is long and complicated.
One day, I was sent to care from a man who was dying. I was told he was very confused and would need a lot of care. He was in hospital.
I arrived, on time and was shown into a side room.The man was almost comatosed and required no intervention at all.
I hadn't brought anything with me to read. I sat in this bare room. His bed was in front of the window, which was frosted anyway. The walls were bare and within about 10 minutes, I was bored silly.
I found a copy of Gideon's Bible, which is the New Testament only, on a shelf. I decided to read it.
Now, like most people, I'd been brought up on a steady drip feed of excerts from the Bible and really thought I knew what it said. So, I emptied my mind and just read it from the begining. It took about 2 hours to read each gospel.
I won't tell you what to think or believe, that isn't my place. I will tell you to find a quiet place and read the Gospels, from the first, Matthew.
I will say, I now know. I have no doubts. Just read it, the New Testament, from the begining.
