A short video entitled The Purpose of Temples discusses the importance of the concepts, teachings, and truths portrayed in the temple endowment ceremony (as administered by the LDS church) in terms of our journey back into God's presence while in this life. What is portrayed in the endowment ceremony can become a reality in each person's life as they navigate the same challenges and opportunities as faced by our first parents, Adam and Eve. The endowment ceremony teaches that the pursuit or result of our faith is to come into the presence of the Lord while mortal and receive the promise of Eternal Life from Him personally, rather than being a mere promise that these things will come true only in the afterlife. This video has been posted to the Testimonies page as well as in the FAQ.
Please note: This video does not discuss specifics about the sacred symbols and teachings of the LDS endowment ceremony.
