3 Nephi 19:7-8In Judaea, the disciples of the Lord also repeated his teachings in their missionary outreach, whose directions we find in JST Matthew, chapters 5 through 7 inclusive.
7 And the disciples did pray unto the Father also in the name of Jesus. And it came to pass that they arose and ministered unto the people.
8 And when they had ministered those same words which Jesus had spoken--nothing varying from the words which Jesus had spoken--behold, they knelt again and prayed to the Father in the name of Jesus.
We find that these things are also what the Church is supposed to be teaching (D&C 42:12-13, D&C 52:9).
 Notice that Luke 6:30 - "Give to every man that asketh of thee; and of him that taketh away thy goods ask them not again." - which are actual commandments of the Lord - has not been taught by any Church leader within the scope of LDS.ORG's search function, and remember that keeping all the commandments of Christ is necessary to be exalted.
