LUKE 12:39–40
THE UNEXPECTED HOUR
Text – Luke 12:39–40
39 Be sure of this: if the master of the house had known the hour when the thief was coming, he would not have let his house be broken into.
40 You also must be prepared, for at an hour you do not expect, the Son of Man will come.”
Historical and Jewish Context
In the ancient world, homes were vulnerable to break-ins, particularly at night. Families often guarded their houses carefully, especially during harvest seasons when food and goods were stored. Jesus uses this familiar scenario not to portray God as a thief, but to emphasize the element of surprise. Jewish apocalyptic expectations often described the day of the Lord as sudden and unexpected. By calling Himself the “Son of Man,” Jesus draws from Daniel 7:13–14, where the Son of Man comes with divine authority. His listeners would understand that spiritual readiness—not fear—was His primary message.
Catholic Theological Perspective
Jesus teaches the necessity of continual preparedness for His coming—both His final coming at the end of time and His daily visits through grace, events, and the sacraments. Catholic theology emphasizes that vigilance is rooted in love, not anxiety. The Christian awaits Christ with hope, living each day faithfully through prayer, sacramental life, works of charity, and moral integrity. The “unexpected hour” reminds believers that every moment is an opportunity for holiness. This teaching also supports the Church’s understanding of the Last Judgment and personal judgment at death: readiness means living in a state of grace.
