Late in 1973 I finished my B.Sc. honours degree in physics at the University of Western Australia. After that I was not so sure what I should do. However, that summer (Nov-Dec 1973) I visited my Catholic girlfriend out in the country (which Australians call the Outback) on an aboriginal mission where she was working. I think she could not fully comprehend what was going on in my mind, though she was happy I was no longer an atheist but had become a Catholic. (We were engaged to be married when her service ended.) I grew to understand later that her service to God was some religious duty instilled in her by Catholic parents and the Roman Catholic Church, and not as a result of a new heart from a ‘rebirth in Christ’.
At that time, while working out there, I met a Christian guy who told me about David Wilkerson and his work amongst the New York gangs and drug addicts, where many were miraculously delivered from drug addiction and violence through Christ. David Wilkerson was (now gone on to be with the Lord) a born-again Christian pastor who trusted God for miracles to change the lives of many young people on drugs through the miraculous power of the Holy Spirit.
