John Nelson Darby emphasizes the individual responsibility of believers during Christ's absence, using the parable of the ten virgins to illustrate the necessity of being prepared with oil for their lamps. He explains that while all the virgins went out to meet the Bridegroom, only those with oil were admitted to the wedding feast, highlighting the importance of genuine faith and readiness. The sermon also discusses the parable of the talents, where the faithful servants are rewarded based on their understanding and trust in their Master. Darby warns against complacency, noting that even the faithful can fall asleep and forget the Lord's return, but they must remain vigilant and faithful in their service. Ultimately, he concludes with the assurance that those who have received the message of Christ will be judged favorably, while those who reject it face eternal punishment.
