NOTES for Mat 25:10-13
The vigilance to which Christ calls His disciples is constant readiness to meet the One who comes in the name of the Lord. The "wise virgins," whom the Lord sets before us as an example, prepared for a long wait and so could remain in the appointed place as long as the Bridegroom pleased. That is why they are ready for this meeting at any moment, even if the Bridegroom "was delayed." The "foolish" virgins, however, at the hour when the Bridegroom's arrival caught them, turned out to be occupied not with waiting to meet Him, but with getting ready.
The Lord is saying, then, that we do not have the option of being occupied with ourselves and with our own affairs and problems. The coming of the Kingdom is possible at any moment. From the beginning this thought inspired Christ's disciples to live in righteousness "already today," without putting off the cleansing of the heart until "later." At the same time, it is curious that when the Lord speaks about waiting for the coming of the Kingdom, He still hints to us that the Bridegroom "was delayed," thereby warning us against an excessive fascination with eschatology.
