If he wants people to believe in him, and know his will, it's his job to provide clear evidence, like the evidence for a heliocentric solar system or germ theory. If he's going to hold people accountable for their actions and beliefs, it's his moral duty to do so.
Well, that's the thing isn't it..
There
is clear evidence .. 50% of people are Christians and Muslims. They consider that there is clear evidence.
Atheists have decided that the evidence is not reliable.
Almighty God knows what is in our hearts.
He knows
WHY we might not accept what believers accept as evidence. It might not be as simple a case as "no gods can be proved to exist" .. there might be deeper underlying reasons why a person rejects a higher authority.
If a person truly believes that believers are deluded, and that there is no higher authority, then they will live their life accordingly.
We all have to bear the consequences of our intentions and actions in this life.
The main difference between belief and disbelief, is that the consequences continue to be felt after death.
