Ellen White is saying that the Ten Commandments (which are in the ark of the covenant) will be displayed during the last days (most likely after the Sunday Law has been passed).
The Ark Files documentary is absolutely amazing. Because of the 3D clips, it almost feels like you are there.
Amazing, amazing stuff. Highly recommended.
