A prayer cannot accept Jesus Christ as its Lord and Savior. Just mentioning Jesus in a prayer doesn’t make it Christian.
Tell it to the 4th Circuit. Whatever diety a prayer "mentions" or if it doesn't mention any diety, it presumedly is petitioning somebody. So it's religious regardless of the content. How does a Court go about deciding the constitutionally permissible content of a religious prayer without establishing some sort of religion in the process? It's an absurdity.
