The majority who get such treatment are turned off religion for life. Most Christians come to a point of commitment as adults. Many have had little or no contact with the Christian faith in childhood. Those that did attend Sunday School can testify to its very minimal influence upon them. People become Christians, not because of pre-conditioning, but because they have a personal encounter with Jesus Christ that transforms their life.
Christian belief is based on objective evidence.
Christians believe that God has sought after mankind in Jesus Christ, who through his death and resurrection, has made it possible for us to enter into an eternal relationship with him. If Jesus did not exist, or if his body is still in a tomb in Palestine, then our belief is without substance. Only then could a person suggest that our faith is a psychological illusion. It is not possible to argue that we are a group of socially maladjusted freaks or mentally handicapped morons. Too many people of differing social status and mental capacity follow Jesus and so demonstrate Christian objectivity.
