19 And again, verily I say unto you, if a man marry a wife by my word, which is my law, and by the new and everlasting covenant, ...Ye shall come forth in the first resurrection; ...and shall inherit thrones, kingdoms, principalities, and powers, dominions, ...and they shall pass by the angels, and the gods, which are set there, to their exaltation and glory in all things, as hath been sealed upon their heads, which glory shall be a fulness and a continuation of the seeds forever and ever.
20 Then shall they be gods, because they have no end; therefore shall they be from everlasting to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be gods, because they have all power, and the angels are subject unto them.
21 Verily, verily, I say unto you, except ye abide my law ye cannot attain to this glory.
22 For strait is the gate, and narrow the way that leadeth unto the exaltation and continuation of the lives, and few there be that find it, because ye receive me not in the world neither do ye know me.
(Doctrine and Covenants 132:19-22)

This would seem to be a FUNDAMENTAL requirement for MORMONs; would it not?
