The holy Jerusalem hath no need of the sun, neither of the moon, to shine in it; the glory of God shall lighten it, and the Lamb is the lamp thereof (Rev. 21:23 and 22:5).
Most of us, as well as our scientists, might mock and giggle at the notion that a mere lamp could replace the light of our gigantic astronomical sun. But this biblical phrase describes something much deeper and profound than any electromagnetic spectrum.
The statement actually represents a change from thermodynamics to Theo-dynamics. Theo-dynamics represents the “light” of God’s Truth, which lets our spiritual eyes see.
The “New Jerusalem” represents a new mental state in humans where they become more receptive to this inner light from heaven.
This heavenly light and those who are influenced by it are not affected by the thermodynamics or brightness of the physical sun. So it is not needed by men and women who are becoming more spiritual—which is God’s intention.
Elevating one’s mind to appreciate some of these higher meanings (from out of the literal sense of God’s Word) is the beginning of receiving and understanding the light of this sacred lamp—which can enlighten (psycho-spiritual light) our whole inner world!
Furthermore, how else can the “Lamb” be called a lamp unless it referred to the spiritual influence of innocence and goodness that shines from the Lord?
