Isaiah prophesied about the effect of losing knowledge about God. He wrote: “Therefore my people are gone into captivity, because they have no knowledge: and their honourable men are famished, and their multitude dried up with thirst.” (Isa. 5: 13.)
This is an apt description of people when they are not “fed” with truth and light.
In contrast, Nephi wanted the Latter-day followers of Christ to have a “feast” to consume while toiling in this fallen, difficult time. But Nephi notes the “feast” will come to us from hearing the words of “angels” and not from the “arm of flesh.” Nephi taught us: “Angels speak by the power of the Holy Ghost; wherefore, they speak the words of Christ. Wherefore, I said unto you, feast upon the words of Christ; for behold, the words of Christ will tell you all things what ye should do.” (2 Ne. 32: 3.)
Whether we are to “feast” or be “famished” is up to us. Seek, ask, knock: it will be opened. Stay content, do not ask, seek, or knock: you will remain dried up with thirst.
