I understand what Islam says about the purpose of our life. It's to be tested.
But I've never heard anyone talk about the purpose of God. What's his purpose? Is his purpose solely to test us? Is all the beauty of his creation and that of the hereafter solely so that we can be tested?
I find that notion to be very disrespectful to the mightiness of God, but I can't find an alternate answer. And strangely, no one talks about it.
(EDIT: This question is usually avoided by saying "Oh, you can't understand the nature of God. It's beyond your comprehension". I find that to be very unfair. Why am I given the ability to ask what the purpose of God is but not the ability to understand the answer to that question).
