In the Parable of the Ten Virgins, Jesus teaches that His return will come at an unexpected time and that only those truly prepared by genuine faith will enter His kingdom. Though all ten appeared ready, only five had the necessary oil, showing that outward religion and good works cannot substitute for true belief in the gospel. The parable warns that many who profess Christ may be shut out, urging all to remain watchful, ready, and grounded in saving faith.
