My parents changed their religion in the mid 1930's after their firstborn was killed aged 5. They went along with a proselytizing group who promised them their child would soon be resurrected on to a paradise earth. This meant that when I was born many years later, I and my siblings were taught that religion, and to have the same expectations. The good thing about that was that my parents taught me to memorize lots of Bible verses. Not so good was that, because I had the religion's beliefs drummed into me and had no knowledge of any other beliefs, I became a keen practitioner. But on the plus side it also meant we were sheltered from many of the vices of the world as this was an exclusive group that did not mingle with others.
However, when my mother died, her firstborn was still in his unmarked grave. Many years later, my father also died disappointed. In the meantime, I had re-read the Bible and discovered that many of the things they had taught me to believe were simply not true. In my mid-20s I decided to reject the false teachings, stick to the true ones, and because of that, I had to leave that denomination. But the grounding they had given me in the Bible continued to serve me well, as I could then stick to what the Bible said and join a local Christian group that taught the Bible diligently.
My parents were sincere and caring, so that was the main factor in having a good upbringing. They also instilled in to me a respect for the Bible and that continues, to this day. They had been misled in certain respects, but I could never hold that against them, given the circumstances. I am very grateful for my parents' diligence in trying, to the best of their understanding, to help me respect God and His word. Spiritually, all that was wrong with my parents was that they did not have Jesus in the right 'place'. Once that became clear to me, the adjustment changed my life forever, and for the better.
