Here is an audio by the late Walter Martin entitled: Reasons for Faith. For those unfamiliar with Walter Martin:
The late Dr. Walter Martin held four earned degrees and received his education at Stony Brook School and Shelton College. He completed his Master’s degree at New York University, and his Ph.D. at California Western University. He authored twelve books, six booklets, and scores of articles. His tracts have been translated into a number of languages and circulated in the millions of copies around the world. He was a recognized authority on religions having their origins in the United States. Dr. Martin was best known for his popular open-radio format show, “The Bible Answer Man” which focused largely on Christian apologetics. He is widely accepted as the “father” of the Counter-Cult Movement. Dr. Martin went home to the Lord in 1989. (from Blue Letter Bible)
