The Ten Virgins all had their robes on, white robes of purity, claiming to be Christians. Five were foolish. The Lamps they carried represent the Word of God (Thy Word is a Lamp unto my Feet). But Five had no oil (Holy Spirit). Jesus told them Depart from Me, yes that work iniquity (lawlessness) I never knew you. Its that simple. Many Christians today make a mere profession of Christianity. With no inward change.
