Wallace was a self-described “angry” atheist until his mid thirties. After visiting Saddleback Church, he decided to use the Forensic Statement Analysis (FSA) to investigate the gospel of Mark. If the FSA works for suspects and witnesses, Wallace thought, why not for the Gospel of Mark? He had become a bona fide expert at judging the veracity of a statement through examining the author’s use of language. Within a month of studying Mark’s Gospel, Wallace concluded it was an eyewitness account of the apostle Peter. This was the beginning of his conversion to Christianity.
