Before Jesus came onto the scene people were dying left and right without being saved from the wages of their sins. Then when god finally decided to set his plan of salvation into motion it was like molasses running downhill in winter. Only a smattering of those in the mid-east and those in Rome eventually heard about salvation through Jesus (Christianity didn't become the accepted religion in Rome until 300 CE). Slowly, over hundreds of years, people of other lands were introduced to the "message," some not hearing about salvation through Christ until the twentieth century. In the meantime the omnipotent god of Abraham turned a blind eye to the millions upon millions of people who had died and were dying without benefit of the death of his son.
So what could have been going on in gods mind? What kind of mind lays misery on an entire species of creatures and then provides a cure that is so confined and works so slowly it only affects a pitiful percentage of them? Were these clueless people somehow undeserving of salvation? Was this some kind of experiment of god's, using the unaware as a control group?
Considering that salvation is such a big deal, to me a decent being would never withhold such a gift. I know of people, myself included, who would never be so merciless. So, I can only conclude that when it comes to the truth of the matter, god simply doesn't care. He eventually threw a bone to his creation and doesn't care who sees it or not.
Of course, if I've missed an important element here, I'm all ears.
