In this parable both the wise and foolish maidens slept; but the wise ones were prepared to act immediately when they were unexpectedly awakened. The foolish maidens were not prepared. The wise maidens had an extra supply of oil for lighting their way the reception venue, symbolic of the Holy Spirit (Zechariah 4:1-7).
Oil is fuel, it lights when it is burned in a lamp – where the Spirit of God is there is light. Light guides.
