A vision you cannot hand to another person in specifics stays a feeling, and feelings never get built.
What the Spirit gives arrives whole and invisible, and invisible things cannot be delegated. Break it into courts, side rooms, and treasuries, and a thousand workers suddenly have somewhere to put their energy, because attention needs an object before labor can follow it.
A man told he would never build the thing specified it anyway, down to the storerooms, which is what conviction looks like when it stops depending on being present for the finish. Whatever stays general gets abandoned the week after the one carrying it is gone.
