I see these stories as metaphors and symbols.taijasi:
So, in short, what is that? What should we be working toward? Just what is our role in helping to usher in the Kingdom of Heaven on Earth? What do you understand Jesus to have taught regarding these responsibilities?
My answer is that we will only be able to assist in ushering in any "kingdom of heaven" into our earth by first connecting with it inside ourselves.
Only then will we have more than the vaguest clue as to what to do from there.
Plus, until people actually make that connection they will not really care enough to do anything significant.
Once a person develops "a heart of flesh" as opposed to one of stone, then they find that they actually do care, they care about a great many things.
Caring is the first step.
