Jesus is the bread of life (John 6:35, 50-51). Wheat, when it dies, brings forth life (John 12:24). Jesus gave us the bread recipe, though not the measurements.
Take some wheat (Matt 3:12). Throw out any tares (Matt 13:25). Add oil (Matt 25:3; Mark 6:13). Add water (John 3:5). Add salt that is pure (3 Nephi 12:13; Luke 14:34). Add leavening (Luke 13:21; 1 Cor 5:6).
There are hidden meanings here, pieces of a puzzle. Separately, they don't mean as much, but put them together and bake them in the fiery furnace of affliction or in the refiner's fire and you come out with a finished product, if you will. One worth saving. One worth partaking of in the household of God just as food becomes one with us when we partake of it, thus becoming one with the Gods - thus we can all share the Mind of God and be one.
