Why do the heathen rage?

Why does the heathen rage? Decisions have been made that God does not exist, and therefore not the God of the Bible. They do not believe and have stated unequivocally that He does not exist. Yet, there seems to be a continuous anger toward what they believe does not exist. Text books are printed for Universities, Colleges, schools around the world, trying to explain all that we see, as if all sprang up be magic. They demonstrate their animosity to all what retain faith in what they doubt.
