morning thought

How often are we asked to do something, by our parents or leader which we had already done? I was thinking about that because I was in Nephi chapter 19 where he talks about the record he already made, but then God commanded him to make another record and he explains that he can think of reasons, but that does not explain why nor should the why be necessarily known, obedience does not require knowledge,  infact it is a common phrase that faith proceeds the miracle... just yesterday I was listening to a talk where someone was talking about the ordinances and how they are performed at an alter, but even Adam when asked why this was done said that he did not know any more than that God commanded it.

2 thoughts or directions for further thoughts:

1) all of the times in the scriptures where the doer knew not how or why but still accomplished the thing.

2) How mankind likes to criticize faith as blind obedience.
