The closest I can recall, was one day during class (on a Saturday) something happened that still sticks in my mind.
I was reading a bible (no way to know where it came from, because there wasn’t another one in the whole room).
There was something about Jesus... The nun teaching the class came over and asked me what was I reading... I told her and was trying to ask a question.
She closed the Bible on my hand and told me I didn’t need to read the Bible as the church teachings were all I needed.
To this day, I’m not 100% what I asked...fairly sure it was about Jesus dying...for what....
My spirit wasn’t quickened until decades later, after accepting Jesus during a church service held at a Baptist church.
Turned my life upside down. Faced stuff after the fact, that were it not for Jesus, I’m sure I wouldn’t have made it through....or at least made it through...intact.
It all goes down to where the Word is spoken and if it’s not spoken to where God leads one to find it....
I’m so sorry the nun did nothing to help you find Christ. Yet a seed was planted and you were searching. You asked, why did Jesus die? Thank God you found Him (He found you) years later.
