you certainly have a varied and multifaceted background stringsinger, - mine not nearly so.
my parents were not practising believers.my brother and I only attending sunday school for a short while but soon bored with it.
as a young teenager I considered myself atheist, for no profound reasoning, but a friend invited me to a youth meeting at the local Pentecostal church. naturally speaking ,I don't know why I went then ,or continued to attend that,, and the usual service, for a long time still declaring myself an unbeliever.
I suppose it could be put down to a sense of belonging, and certainly I was welcome there.

my mindset began to change and I read about fulfilled bible prophecy and the unlikeliness of evolutionism, though the material then was a lot less than now, and eventually I believed in God.
it was a while later when I responded to the" alter call "professing faith in Christ as my lord and saviour.
I did not feel much different, though enthusiastic.
there used to be "waiting meetings" and at one of these I had a very powerful experience of speaking in tongues ,which I think further cemented my faith.
I don't consider it easy being a Christian but I have no doubt of my faith in God ,though some things in the bible have needed working through.
