The God of Isaac?
-The same God who according to Hebrew legends, told Abraham to sacrifice his only child, and then an angel magicly appeared and grabbed Abraham's hands at the last moment? That psychotic and insecure God? (And yes I know it was just a test of Abrahams obedience, and an allegory that was supposed to show that God wouldn't want anyone to sacrifice their own child, he would only sacrifice his own child many years later.)
In the mean time, blood sacrifices of animals continued for another 5,000 years. Discovery of logic and reason takes a long time to accept for unthinking photocopy machines.
Anyone who was caught trying to sacrifice his child to a god today, would be thrown in prison, and branded as a lunatic. Fortunately, most religions of today have given up on blood sacrifices. They have made various reasons for it, mostly because they finally realized that it was immoral and unethical to kill people. And they discovered science, and the realization that sacrificing people animals, etc, didn't appease the weather and volcano gods, or the gods of thunder and lightening.
The Muslim religion still believes in blood sacrifice, unfortunately. They are where the Hebrew religious sheep were about 5,000 years ago. The sooner all religious superstitions are overcome by science, the better.
Just curious, are you one of these Christians who still believes that God punishes people with tornadoes, hurricanes and volcanic activity?
