By that standard, Joseph Smith is a good prophet to follow.
You can't on the one hand say that Smith is a "good prophet to follow" after he failed the Deuteronomy 18 test above. You can't on the one hand claim that "living prophet" is vital and that D&C reflects some of those prophecies, when D&C 114:1 unveils a false prophecy.
"Verily, thus saith the Lord: It is wisdom in my servant David W. Patten, that he settle up all his business as soon as he possibly can, and make a disposition of his merchandise, that he may perform a mission unto me next spring, in company with others, even twelve including himself, to testify of my name and bear glad tidings unto the world." (D&C 114:1)
Date of "prophecy": 4/17/1838.
Date of mission mentioned in prophecy: "that he may perform a mission unto me next spring [1839]."
Date of Patten's death: 10/1838.
Bottom line: God knew who would die and who wouldn't. He was not surprised by Patten's death. God doesn't waste his breath by uttering specific names who will not be performing any mission to him...
How do you know the mission was to this world? Telling him to settle his business and dispose of his responsibilities in advance was not all that common, it was a kindness from the Lord to warn him to put his affairs in order.
The difference between the interpretations is simple, I know Joseph smith to be a prophet by personal revelation. You believe he was not a prophet. I look at the prophecy and say how was this fulfilled? You look at it and say “how can this be used to prove Josph Smith was not a prophet?
We both will see what we expect to see.
