Hungry Enough to get Something New

Meanwhile Moses was shepherding the flock of his father-in-law Jethro, the priest of Midian. He led the flock to the far side of the wilderness and came to Horeb, the mountain of God. Then the Angel of the Lord appeared to him in a flame of fire within a bush. As Moses looked, he saw that the bush was on fire but was not consumed. So Moses thought: I must go over and look at this remarkable sight. Why isn’t the bush burning up?

“Do not remember the past events,
pay no attention to things of old.
Look, I am about to do something new;
even now it is coming. Do you not see it?
Indeed, I will make a way in the wilderness,
rivers in the desert.”
(Isaiah 43:18-19 HCSB ©®)

Is it possible that Yahweh only does new things in places where there are hungry people? Is it possible that even in those places, only those who are hungry enough for an untried menu, an unfamiliar dish, will taste and find the Lord there?
