These verses ask the deniers whether they believe in God’s supreme power or not? If you do not then look at the universe and see the skies, the established stars , the galaxies and the total formation and then look at the earth and see its creations and mysteries and observe how a perfect system rules over everything.
Is it possible that you observe all these signs of God’s omnipotence and then have doubts about Him?
If you believe in His perfect power and authority then how do you doubt about the Day of Judgment and His power to re-create the dead by declaring it odd and unacceptable?
