Let me explain:
Our definition of God can be summarized by the following:
- Someone who is just
- Someone who is really kind
- Someone who is all-powerful (can cause anything to happen)
Now, if such a God was there, why would there be suffering in this world? Why would people be born poor?
Why would disease exist?
Some argue that God punishes man for doing wrong. Then why are some babies born with serious health problems? They have not yet got a chance to do wrong. Things done in the previous birth? God is all powerful. He could have prevented anything wrong being done.
Why should God prevent someone from doing wrong? Because he is kind. If he can, he should not allow anything wrong from happening, mindful of the fact that if the individual does something wrong, he will have to face problems in the future.
Some people have said things like he does these things to increase his glory. That sounds very un-Godlike. He lets people suffer to increase his own glory? I don't think that's a convincing explanation.
That's why I am convinced that there cannot be a God that matches the conventional definition.
