For all who will have a blessing at my hands shall abide the law which was appointed for that blessing, and the conditions thereof, as were instituted from before the foundation of the world.
5 And verily, verily, I say unto you, he that receiveth my gospel receiveth me; and he that receiveth not my gospel receiveth not me.
6 And this is my gospel—repentance and baptism by water, and then cometh the baptism of fire and the Holy Ghost, even the Comforter, which showeth all things, and teacheth the peaceable things of the kingdom.
. . .
22 And he that receiveth these things receiveth me; and they shall be gathered unto me in time and in eternity.
Doctrine and Covenants 39:5-6,22
Look unto me in every thought; doubt not, fear not.
Behold the wounds which pierced my side, and also the prints of the nails in my hands and feet; be faithful, keep my commandments, and ye shall inherit the kingdom of heaven.
Doctrine and Covenants 6:36-37
Note how our ability to look to Christ and banish doubt and fear is connected to the Atonement. The reason we can be completely confident in Christ is because we know that he has atoned for our sins and our weaknesses.
I beheld round the throne holy angels and hosts,
And sanctified beings from worlds that have been,
In holiness worshipping God and the Lamb,
For ever and ever. Amen and amen.And now after all of the proofs made of him,
By witnesses truly, by whom he was known,
This is mine, last of all, that he lives; yea, he lives!
And sits at the right hand of God on his throne.And I heard a great voice bearing record from heav’n,
He’s the Saviour and only begotten of God;
By him, of him, and through him, the worlds were all made,
Even all that [careen] in the heavens so broad.Whose inhabitants, too, from the first to the last,
Are sav’d by the very same Saviour of ours;
And, of course, are begotten God’s daughters and sons
By the very same truths and the very same powers.
Joseph Smith, commenting on Doctrine and Covenants 76, including verses 21-24
