I went to his website, and didn't quite find the answer to that question, but I found an article where he explains how he became the man he is today. It is quite amazing. And it is a relationship with the Living God, not religion, that filled him. It is a relationship with the living God that influenced William Wilberforce, Abraham Lincoln, and the heroes of IJM who have done so much good-- who have righted injustices and evil and brought harmony and peace. While the skepticism at religion, especially fundamentalism, is understandable, I hate to see people arrogantly belittling my God, when what they are angry about is politics. Ravi's story encouraged me to remember His ultimate, transforming power.
RZ: I came to know Christ at the age of 17 while living in New Delhi, India, where I was reared. My father worked for the Indian government. Growing up in India, I faced many struggles, not the least of which was academic competition in a highly stratified culture. One day I realized that I really didn’t have any meaning in life. So, at the age of 17, I attempted to take my own life by poisoning myself.
Then, when I was recovering in a hospital, a friend brought me a New Testament. Because my body was dehydrated, I was receiving fluids and I could not hold the New Testament in my hands. The Scripture read to me was John 14, where Jesus said to His apostles, “Because I live, ye shall live also.”[16]
I knew that whatever else that Scripture meant, it meant more than physical life. I said, “This is the life that I have yearned for.” I made my commitment to Jesus Christ and have never looked back, except to remember how He rescued me and put a new song in my heart—new hungers, new desires, new life. He put a new hunger into my heart, a hunger for God Himself. Prior to that I was more concerned about success, good grades, good jobs. I was constantly thinking about what others thought about me. God refocused my attention on Himself.
I knew that this was not some kind of motivational therapy but a new kind of relationship. There is a difference between a person who hungers for love and one who has found love. God put in my heart that great hunger for Him, even as I knew that in Him I had already begun the process of being filled. Before I heard those Scriptures I was completely empty. Now I had found through the Person of Christ how I could be filled.
