Okay... God wants to save as many souls as possible?
So why did he leave a book written by people 2000 years ago, knowing there are so many lies and falsehoods in the world and millions of people would doubt it?
Why doesn't he give tangible evidence every day or once every 10 years?
The majority of people in the world don't believe in God or believe in other religions. Would God allow that to happen in the world knowing that most people would go to hell in that case?
Leaving a book as evidence that you are the right God doesn't make sense, knowing that all religions have the same books and that it will lead millions to fall into the wrong religion. I don't think a God of perfect intelligence wouldn't take that into account
