We in this world who are unbelievers or false professors, are walking in Belshazzar's' shoes, as the devil we believe and tremble but are not doer's of God's word. So it's not a holy fear we have, as the Pharisees we reject or fight against the unknown, that we don't understand we reject instead of submitting ., some as Peter said of those hearing Paul wrestle with the scriptures to their own destruction.
