If I am a non-believer or apostate from Islam, I suppose this sura applies to me:
2-7: Allah has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment.
If Allah (and not myself) is the one, according to this sura, responsible for my lack of belief, by sealing my heartemotion and senses necessary for believing (heart, hearing, and vision), why is it me who will be punished for it? If God is omnipotent, why am I responsible for his interference into my disposition towards believing? If he is omnipotent, there should be nothing in my power to be done about it.
