Why does God Want Humans In A State Of Ignorance ? In my opinion that's what dictators and other evil people want If God Really Was good he would have made humanity with the ability to understand and know everything that there is to know.
First, I think this is a physical limitation on the human brain.
Second, if everyone knew everything and understood everything, there would be no diversity in thought, there would be no challenge, no advancement, no progress at all. Therefore the lack of knowlege and understanding is not necessiarly indicative of an evil god, it also indicates a god which values diversity and improvement.
From the bible... Genesis...
4:6
And the Lord said to Cain, Why are you angry? and why is your countenance fallen?
4:7
If you do well ( improve ), shall you not be accepted? and if you do not well, sin lies at the door. And to you shall be his desire, and yet you may rule over him.
You may rule over your sin and desires = improvement.
There's other issues with god bestowing perfection of any sort on creation, but, hopefully what I wrote above is an adaquate answer to your question.
