The idea of being blessed in a small space takes a lot of getting used to ( partly because we are greedy and dissatisfied by nature and partly because it is a struggle to gain our daily bread from our small patch )
But this is Gods wisdom and plan for us -
That unbelievers can' t see it doesn't surprise me . They want walls where maybe none are needed or wont accept walls where they are needed ( roles and responsibility and accountability )
God surprises us with his ability to supply and break through the walls .
