I believe that godliness is obedience to eternal laws. We learn that -
"...he who is not able to abide the law of a celestial kingdom cannot abide a celestial glory." (Doctrine and Covenants 88:22)
"...the earth abideth the law of a celestial kingdom, for it filleth the measure of its creation, and transgresseth not the law—" (Doctrine and Covenants 88:25)
"...again, verily I say unto you, that which is governed by law is also preserved by law and perfected and sanctified by the same." (Doctrine and Covenants 88:34)
"All kingdoms have a law given..." (Doctrine and Covenants 88:36)
And so forth.
