The Holocaust was due to God, and Hitler ruled by the consent of God?
Really?
Yes. Just as the fall of the Jewish Nation in the Bible was by the consent of God; the slaughter of children (2 and under) in order to destroy Jesus, the hardening of PHaroahs heart, the nailing of Jesus to the Cross - everything happens because of God. Jesus says this at his sham trail. Why? Because we - as humans - learn the difference between good and evil, and good things will come out of the hard times, just as a excellent sword is thrust into fire and beaten and honed into a fine weapon, so are we as a people thrust into the fire. The weak ones break - the bad metal. But the good metal become better.
