Lovers of the Lord Jesus, the bridegroom, long for his return.
These took their lamps.

The lamp represents the Word of God; as the Psalmist says: "Thy word is a lamp unto my feet".

(Psalm 119:105) Part of these virgins were wise; therefore they took oil in their vessels.
The wise represent the bride class, the faithful ones; while the foolish ones picture a class of greater numbers who will not be of the bride class, but will be born on the spirit plane.

While these have waited for the coming of the Lord, the foolish ones have been indifferent.

They have had no oil, have not had the spirit of the truth, the loving zeal for the Lord and his cause; hence they have been negligent.
