Christ is the one who opens the heavens. (Ether 4: 9.) It is at His command the heavens open and close.
Those to whom the heavens remain closed and to whom angels no longer minister are practicing a faith which is vain. (Moroni 7: 37.)
Nephi warned us against a faith which claims Christ had finished His work and given His power to men. (2 Ne. 28: 5.)
Neither God nor His Gospel change. (Moroni 8: 18.)
I care nothing for men or their precepts. Man's precepts will only condemn us at the last day. (2 Ne. 28: 26-27.) I care only about Him at whose command the heavens are opened; and for those whom He sends through the opening He causes to occur. All else is vanity-- because it cannot save.
