As a child growing up in a works-oriented church, Dr. Chetta believed that he was "OK" as long as his good deeds outweighed his bad deeds. As a senior at Louisiana State University, he was challenged by Walt, a fellow student, with the simple question, "Marc, if you died tonight, where would you spend eternity?" Though initially regarding it as "the most off the wall question ever," he was haunted by this question for two weeks. Walt invited him to a Campus Crusade for Christ action group (Bible study), to which Dr. Chetta responded, "Sure, what have I got to lose?"
Over the course of nine months, Dr. Chetta and Walt stayed up late into the night discussing the validity of the Bible. Dr. Chetta's biggest objection to the truth of the Bible was evolution vs. creation. Majoring in zoology and minoring in chemistry, preparing for medical school, he was heavily steeped in evolutionary philosophy. Walt gave him several books to read, including Dr. Duane Gish's Evolution: The Fossils Say No and The Genesis Flood by Drs. Henry Morris and John Whitcomb. He was amazed at the good science presented in these books and was angry that he had never been exposed to any alternative views in his fifteen years of education.
After another lengthy discussion with Walt, his friend stood up, closed his Bible, and said, "Marc, you want me to persuade you into the kingdom of God. You have inched up to the line and you want me to pull you across. At some point, Marc, you must step across the line by faith. I'm leaving. You are at the crossroads. The monkey is on your back." With that, Walt walked out the door with Dr. Chetta yelling for him to stop. But this forced a decision for Dr. Chetta, so he knelt down, confessed his sins, placed his faith in Jesus Christ, and asked God to save him.
Amazingly after salvation his spiritual eyes were opened and all those smoke screens and perceived obstacles to faith dissipated in the light of the truth of the Word of God. He made it a point to read everything he could find on scientific creation, and began to speak wherever he was invited on the evidences for a young earth.
