Joseph Smith 

“The fundamental principles of our religion are the testimony of the Apostles and Prophets, concerning Jesus Christ, that He died, was buried, and rose again the third day, and ascended into heaven; and all other things which pertain to our religion are only appendages to it. But in connection with these, we believe in the gift of the Holy Ghost, the power of faith, the enjoyment of the spiritual gifts according to the will of God, the restoration of the house of Israel, and the final triumph of truth…. As in Adam all die, even so in Christ shall all be made alive;’ all shall be raised from the dead . The Lamb of God hath brought to pass the resurrection, so that all shall rise from the dead. …Christ Himself has assuredly risen from the dead; and if He has risen from the dead, He will, by His power, bring all men to stand before Him: for if He has risen from the dead the bands of the temporal death are broken that the grave has no victory. If then, the grave has no victory, those who keep the sayings of Jesus and obey His teachings have not only a promise of a resurrection from the dead, but an assurance of being admitted into His glorious kingdom; for, He Himself says, ‘Where I am there also shall my servant be’ [John 12:26].” (Teachings of Presidents of the Church: Joseph Smith p. 50-51).
