Numbers 14:1-11

It would seem as though Israel had every evidence that God was with them, and that He was clearly powerful enough for them to trust Him. But that evidence—what He did to the Egyptians; the dividing of the Red Sea; His providing two million people plus with manna every day, with water as was needed, and even quails for them, clothing that did not wear out; and He even provided them with shade during the heat of the day—was not enough.

And their faith evaporated when fears (for their own safety, for the preservation of their flesh, and the satisfying of their appetites) overrode the trust of almost everyone. Their fear overcame whatever level of faith they had, and it motivated rebellion. It led directly to the death of everyone over twenty, except for Joshua and Caleb. Do you get the point?

Fear kills! That is its ultimate fruit.

This illustration here in Numbers 13 and 14 is clear evidence that these people were walking by sight. What they saw were giants, and it intimidated them—as if God was not bigger, greater, more powerful, smarter than giants. So God has to ask, "How long is it going to be before they believe Me?" It is like He says, "What can I do that might give them more faith?"
