The Ark of the Covenant was made by Moses to contain the tablets of the Law and other items. The popular conception of the Ark is that of a simple golden box. This view is incomplete as the box is actually one component of a larger, supernaturally powerful device. It is said to be the sign of the Christ, the Messiah and the Mahdi when this figure arrives.
Many people await Jesus’ second coming, the initial arrival of Messiah or the coming of 12th Imam. When this figure arrives, a powerful device with an unearthly power is awaiting their discovery. It is clear that this device is some form of otherworldly ascension tool that can transmute flesh into light. This is why it is the most coveted device of human history.
