The answer is: Pearl

Rev 21:21

The depiction of the twelve gates in the New Jerusalem being made of pearl is a stunning and intricate image found in Revelation 21:21. Picture this bustling city adorned with exquisite and opulent beauty. The pearls leading to each gate symbolize purity and the precious nature of divine entry—a significant visual for what believers expect as the ultimate dwelling place.

Now, each gate made of a single giant pearl is also intriguingly symbolic. In biblical context, pearls are more than just a luxury item; they were often seen as treasures, and Jesus even spoke about pearls in a parable (Matthew 7:6), showcasing their value and rarity. Isn’t it cool that each gate was crafted not merely to impress but to embody the elevated worth of a heavenly destiny—each one a welcoming entry in this city of God?

Trivia alert: Did you know in ancient cultures, pearls represented wisdom? They were perceived as something so rare that only those with great insight and understanding could obtain them. This fascinating connection might explain why pearls are used here—to echo wisdom woven throughout the journey of faith leading to eternal life.

Also, notice how the entire city is sometimes called "the city of gold," sparking parallels to a life abundant and dignified beyond what we can measure by earthly standards. The image of an ornate city makes anyone dream of a grand reunion of unity and peace, transcending the chaos of earthly life! It's a compelling promise that invites each person to ponder the greatness that lies beyond.
