2 Nephi 33

 Again, teaching the Doctrine of Christ, Nephi explains plainly - 

"I have charity for the Jew—I say Jew, because I mean them from whence I came.

9 I also have charity for the Gentiles. But behold, for none of these can I hope except they shall be reconciled unto Christ, and enter into the narrow gate, and walk in the strait path which leads to life, and continue in the path until the end of the day of probation."  (2 Nephi 33:8–9)

Ordinances and covenants are essential to eternal life.
