My son John.... You have asked me concerning the new & everlasting covenant & how far it is binding upon my people
Thus saith the Lord all commandments that I give must be obeyed by those calling themselves by my name unless they are revoked by my [me] or by my authority and how can I revoke an everlasting covenant[?]
for I the Lord am everlasting & my everlasting covenants cannot be abrogated nor done away with; but they stand for ever.
... I the Lord do not change & my word & my covenants & my law do not & as I have heretofore said by my servant Joseph [Smith] all those who would enter into my glory must & shall obey my law & have I not commanded men that if they were Abraham[']s seed & would enter into my glory they must do the works of Abraham.
I have not revoked this law nor will I for it is everlasting & those who will enter into my glory must obey the conditions thereof, even so amen.
