The Greek word krystallízō, represented by G2929, means to be clear as crystal or to resemble ice. It appears only 1 time in 1 unique verse in the Bible, making its single use highly significant. The term is used to convey an ultimate state of purity, brilliance, and perfect transparency, drawing its meaning from the appearance of crystal or ice.
The sole appearance of G2929 is in the description of the New Jerusalem. The city's light is described as being "like unto a stone most precious, even like a jasper stone, clear as crystal" Revelation 21:11. This quality is directly attributed to the city possessing "the glory of God" Revelation 21:11. Therefore, the word is used to illustrate the city's divine origin and its flawless, radiant nature, which emanates from God's own presence.
Several related words in its immediate context help define the vision of the New Jerusalem:
- G5458 phōstḗr (an illuminator): This word, meaning a luminary or brilliancy, is used for the city's light that is being described as crystal-clear Revelation 21:11.
- G2393 íaspis (jasper): This gem is the specific stone used in the comparison to illustrate the city's light Revelation 21:11. The city wall is also made of jasper Revelation 21:18.
- G1391 dóxa (glory): Defined as glory, honour, or praise, this is the source of the city's light. The entire description is predicated on the city having the glory of God Revelation 21:11.
- G5093 tímios (valuable): This term means costly, honored, or precious. It qualifies the stone-like light of the city, emphasizing its immense worth and beauty Revelation 21:11.
- G3037 líthos (a stone): This word provides the physical object for the comparison. The city's light is likened to a stone, which is then further described as jasper, precious, and crystal-clear Revelation 21:11.
The theological weight of G2929 is concentrated in its single, powerful image.
- Divine Perfection: The crystal clarity signifies a state of absolute purity and flawlessness, which is a direct reflection of the glory G1391 of God G2316 dwelling within the city Revelation 21:11.
- Unobstructed Radiance: The transparency described by krystallízō suggests that God's glory shines through the city without any impurity or obstruction. The city's very structure is a medium for its divine light G5458.
- Ultimate Value: This quality is associated with a "stone most precious" G5093, linking the state of perfect purity and transparency to something of ultimate, divine worth and honor Revelation 21:11.
In summary, G2929 provides a singular yet profound image in scripture. Though used only once, krystallízō powerfully defines the character of the New Jerusalem by describing its light. It conveys a state of perfect transparency and purity, serving as a visual metaphor for the unobstructed glory of God that illuminates the eternal city. The word transforms a physical quality—being clear as crystal—into a descriptor for divine perfection and holiness.
