The imagery of the New Jerusalem, as described in Revelation, paints a picture of a city where the gates are never shut. This signifies a state of eternal safety and openness, where there is no need to fear any threat or danger. In ancient times, city gates were closed at night to protect against invaders, but in this heavenly city, the absence of night means there is no need for such protection. The perpetual daylight symbolizes the continuous presence of God, whose glory illuminates everything, dispelling all darkness and fear.
This vision offers profound hope and assurance to believers, promising a future where God's presence ensures peace, security, and joy. The absence of night also suggests the end of all sorrow and suffering, as darkness often symbolizes these in biblical literature. Instead, there is a promise of eternal communion with God, where His light guides and sustains His people forever. This passage encourages Christians to look forward to a time when God's kingdom will be fully realized, bringing with it the ultimate fulfillment of His promises.
