That is because it is obvious to none with a brain that the "God" character in the Old Testament and the "God" character in the New Testament are entirely different entities. In the Old Testament, "God" is a vengeful, tribal asshole that likes to play mean games with even his most loyal men, like Job, and order the slaughter of even the livestock of the Malachites. In the New Testament, "God" is more like a sideshow attraction, walking on water an stuffing demons into swine.
"God" in both testaments is pitifully unaware of astronomy, chemistry, biology and physics n how they work.
Jesus may have cured half a dozen lepers or so, But modern medicine has pretty much eliminated the possibility of anyone catching leprosy. To become a leper, you have to have a sexual fantasy involving ill armadillos.
The Bible was clearly NOT written by the "God" character.
