How do we watch for the Lord Jesus? Matthew 25:1–13 looks forward to the evening sermon on the coming Lord's Day. In these thirteen verses of Holy Scripture, the Holy Spirit teaches us that we watch for the Lord Jesus by depending upon the Holy Spirit to use the means of His grace to make us ready for heaven. The parable of the ten virgins in Matthew 25:1–13 illustrates the necessity of genuine spiritual readiness for Christ's return, emphasizing that outward participation in the church is insufficient, without inward dependence on the Holy Spirit, through consistent engagement with the means of grace. Wisdom is not merely practical foresight but a moral disposition, rooted in fearing God, while foolishness reflects a self-reliant, superficial faith that also neglects spiritual disciplines. Continual, intentional reliance on the Spirit in Scripture, prayer, worship, and sacraments is vital, as we do not know when it will be too late. Ultimately, the call to watchfulness is fulfilled not only through faithful service in the church but through a personal, ongoing dependence on the Spirit, ensuring that when Christ comes, the believer's life shines with His authentic work, not mere outward appearance.
