D&C 124

 To those who may believe that all you have to do is express that you accept the Savior as your redeemer and you will be saved, the Lord said to John C. Bennett - 

"...let my servant John C. Bennett help you in your labor in sending my word to the kings and people of the earth, and stand by you, even you my servant Joseph Smith, in the hour of affliction; and his reward shall not fail if he receive counsel.

17 And for his love he shall be great, for he shall be mine if he do this, saith the Lord. I have seen the work which he hath done, which I accept if he continue, and will crown him with blessings and great glory."  (Doctrine and Covenants 124:16–17)

I note the "ifs" in these promises.  I note that, as a patriarch and in the temple, many of the promises and blessings are conditioned on faithfulness.
