U- Unveiling the Word

σεισμός fundamentally denotes a shaking or quaking, primarily of the earth, but extends to any violent agitation including storms at sea. Its first New Testament appearance in Matthew 8:24 describes a violent storm that Jesus calms, demonstrating His authority over creation. The word carries profound theological significance, often appearing in contexts of divine manifestation, judgment, or cosmic events surrounding key moments in salvation history. Early church writers used it to emphasize God’s sovereignty over nature and His power to shake both natural and spiritual realms. Today, it reminds us of Christ’s authority over all creation and the coming cosmic transformation when He returns.
