Obviously he didn't ask for any ideas or help with his talk or act nervous (completely opposite of me who has an extreme fear of public speaking). I kept waiting for him to start working on it during the week. Nothing happened. Then Saturday night he spent about 5-10 minutes on the computer and announced his talk was done. I asked him what he was speaking on. "The Nativity". Perfect!
On Sunday morning about 15 minutes before he needed to leave to church to start getting the sacrament ready, I asked him if I could read his talk. It was a very different Nativity Story than I'd expected. It was an unbiased, historical, non-Christian view of Christ's birth and life. I asked him what references he had used to write his talk. Wikipedia. I started laughing and panicking a bit. I showed his talk to Gavin who had the perfect solution. He opened up his scriptures to Luke 2 and had Jack read this account of the nativity story. Jack had found his talk. He read Luke 2 and gave his personal testimony of his Savior and it was amazing!
