I believe that the creator of this universe with the obvious perfection has to be just in order to do all that, in addition ot having the right to do whatever He wants with his creatures since he created them all.
If your wife tied your son up in the basement and tortured him mercilessly for the next 20 years, when you later found out about it would you still love her? After all she surely has the right to do whatever she wants to him, she created him after all. Put aside what the Quran says about this act and think of it purely objectively, does the creator of a life have the right not only to end it but also to torture it?
although he's much more merciful than whatever we think of Him
That's wrong, he is not as merciful as I am. I abhor murder but I accept that it would be possible to drive me to a point where I might actually kill someone. However there is nothing that anyone could ever do which could make me burn them in fire for eternity. Remember that eternity never ends, even 5 billion years is zero compared to eternity. I wouldn't burn Mao Zedong (killed millions of people) for eternity. If someone killed every life in the universe I would not burn them for eternity. There is NOTHING anyone could ever do which would make me sentence them to that.
Therefore I am more merciful than your idea of God, am I not? I can forgive everything whereas God cannot.
Suppose I live in a country with my family and the law says that who takes away an innocent life, his/her life be taken away in return, and the law is so clear about this and my son/daughter knows this very well. Yet my son/daughter commits a crime and kills innocent guy and his/her life gets taken away (may God forbid), how will I feel???
Very sad indeed, as would I. However death is not the same as your flesh repeatedly being burned off and replaced only to be burned off again for all eternity. Do you really think you could love the being that did that to your beloved son?
How can I say that this is injustice?
Avoiding the subject of the death penalty.....
How is an infinite experience of burning in fire justice for anything? Name me the most terrible act you can possibly imagine and I will bet that you don't think the punishment should be eternity in fire.
I don't think we should abandon logic completely! On the other hand, I truely believe there is a certain limit to our human brains, and that's where God's knowledge goes beyond. (to be continued....)
Your argument goes like this:
I don't understand where atoms came from, therefore it is okay for their creator to burn my children in fire. I don't understand it, but it's more clever than I am so it must be okay. If you discovered that God created aliens and then those aliens created Earth + all life on the Earth would you think "They created us, therefore it's okay for them to come and burn the entire planet clean of all life", or is that disgusting privilege reserved only for your all loving god?
If there is a god I would be more inclined to believe "It only does things because they are moral" rather than "Things are moral because God does them".
Tell me, when your soul is in heaven loving the being that is burning your son in fire for all eternity, do you think that soul will be a true representation of you, or some incomplete imitation which must be significantly modified in order for you to accept the situation as it is?
