The most useful thing about this DVD is who is answering.
Shaykh Yusuf Estes did not learn these objections from a book. He held them, argued them from a pulpit, and set out to refute the first Muslim he ever met. When he answers a question about the Trinity, about Jesus عليه السلام, or about why Muslims believe the Bible was altered, he is answering the version of himself that asked it.
That is a different thing from a scholar addressing objections he has only read about, and it is why his material circulates so widely among converts and among those doing da'wah to Christians.
About Shaykh Yusuf Estes
Shaykh Yusuf Estes embraced Islam at the age of fifty, after meeting a Muslim for the first time in his life. Until then he had believed that all Muslims were terrorists and bombers. He was a priest and a Christian musician and minister, as well as the owner of several music stores.
A former preacher against Islam, he despised having to meet a Muslim — but, being a dutiful servant of the cross, he decided he would convert this Muslim who needed to be saved in the name of Jesus. His encounter with that man, and the events that followed, affected him and his family greatly. Eventually he, his wife and children embraced Islam, as did his father and stepmother.
That history is why his lectures land the way they do with non-Muslim audiences. He is not describing objections he has read about; he held them himself, and argued them professionally.
