The power of his presence is mighty. It will fill the temple and no one will be able to enter during the Tribulation. This is a glimpse of the power of God's presence. There were multiple times in the Bible where the presence of God entered a place and people were unable to stand. (1 Chron 6 and upper room in Acts 2) We need to seek His presence and power in our lives. This comes through the filling of the Holy Spirit.
