The Jews who emerged from Egypt in the miracle at the Red Sea, and then who were given the Torah at Sinai, personally witnessed the presence of God -- or so I thought.
How can it be that the same people, shortly afterward, rebelled or openly complained against God multiple times, for example with the manna and with the Golden Calf?
It just doesn't make sense to me that you can witness absolute infinite power and then risk being obliterated by it by doing something said power said specifically not to do.
