Here is another video about preparation for the Rapture.

Preparing ourselves as pure to be His temple for eternity.   She makes an analogy of lining Solomon's temple of the Holy of Holies with gold, that our spirits must be lined with purity which would be a representation of the gold.   Because we are being prepared to be the Temple of God for all of eternity.
