Dunno. God has told us what He has and shown us what He has. I won't reject God's offer of salvation to me simply because I don't understand if or how He will offer it to everybody.
Yahweh the Storm God is certainly taking his time saving the human race.
We aren’t sure of the exact period of time when human beings arrived on the scene, but the general anthropological consensus of the divergence of homo sapiens and their forerunners is roughly between 100,000 – 200,000 years.
So this means Yahweh has witnessed human turmoil for thousands upon thousands of years and sat quietly while humans perished unaware of his existence. Only up until about 4,000 years ago did God decide he needed to divinely intervene. And what does he do? What is his big plan for salvation? He targets a small tribe in the Middle East, yells about how he’s going to murder all their enemies, writes some instructions on stone tablets for them, and explains to them how to properly sacrifice a goat.
Any thinking man or woman should question this deity’s lackluster strategy for salvation.
So after playing favorites and only speaking to one tribe in the Fertile Crescent, this god disappears for roughly 400 years. At some point during his vacation he decides to nix the goat blood offerings forgetting animal sacrifice completely, and that the only way to save the world is through a human blood sacrifice. His plan is to impregnate a virgin, bring into the world a son that is actually himself, have this son preach in one remote area of the globe, and then have himself sacrificed 30 years later… to himself. This is his big plan to spare the world from his wrath.
Another 2,000 years has passed since all this happened and there are still people around the globe that haven’t been reached- which means countless souls have been lost and will continue to be lost without ever hearing about Yahweh. We shouldn’t forget that during those 30 years he was preaching that thousands upon thousands of lives were extinguished which also could have been spared by a hastier plan.
Spreading salvation by word of mouth- I honestly can’t think of a worse plan to save the world. Though I suppose it’s smarter than drowning the entire planet...
