One common way people think is:
“Why doesn’t God simply let everyone know the truth (in some magical way), and since that’s obviously not happening, it means that either God doesn’t care if we know it or not, or that there is no truth to be known.”
Some people even take it further and use it as an argument that there is no God at all. But if we think carefully, the fact that no such mystical introduction to the truth takes place in anybody’s life can be due to one more reason: God doesn’t intend to shove it in our faces in first place.
When we look at all the living beings on Earth, human appears to be unique with its high intelligence and the depth of its free will, such free will that can even be used to cause so much suffering on others.
Why?
This again brings some possibilities to mind: God doesn’t care about humans (maybe even unaware that we exist)? God is not powerful or merciful enough to prevent this? God doesn’t exist? Or God has a purpose in creating a being with free will, and if that is the case, it would be contradictory with any such purpose to interfere with the free will supernaturally. Yes, if it were possible to know the truth in such way, we could still technically keep our free will, but with our intelligence, would it still be free will?
Imagine for a moment that there is indeed afterlife and our permanent place of residence is determined by our actions in world life, and now imagine that it is possible to see in the sky, to which place which person is going after they die, and those who were good are receiving amazing stuff, while the bad ones are entering a “regret-land”. Seeing this, would any human still choose to chase short term entertainment at the cost of being bad to themselves and to others, and losing a great opportunity in afterlife?
