In this world and time period, the holiness of a commandment cannot be revealed until the end of days, because then the world itself will ascend from its physical state, “and the glory of the Lord shall be revealed and all flesh will see together that the mouth of the Lord has spoken” (Isa. 40:5).
The faintly detectable underlying essence that currently only certain select individuals can guess at will become visible to “all flesh.”
In the future, when there will be a qualitative change in the nature of this world, when the physical foundation of this world will be completely transformed, when the divine essence will be revealed within the reality of this world, then, instead of a world in itself, everyone will see that “the mouth of the Lord has spoken” the word of God that animates and manifests all of existence.
