When my son was 13, he established a new relationship with his father and started questioning Christianity. He started spending alternate weekends with his dad, and would return as a carbon copy for a couple of days. His dad had become a self-made success. His dad instilled an ethic of pride in my son and encouraged him in all things. This was good for the timid side of my son; he was playing sports and excelling in things like student government at school.
It was during this period that my son began questioning Christianity and doubting his faith. The simple message no longer worked for him -- he started challenging everything from an intellectual basis. I had our family change to a more youthful, Bible-based church, and I focused my daily prayers on protecting my son from evil influences.
