To me it's kinda like having a child and then saying to it "I have created you, now be obedient to me and worship me otherwise you will be punished for eternity."
It doesn't work to analogize, except only superficially, from the human parent-child relationship to the God-creature one. God is in an entirely different category from you or I. Drawing too-great parallels, parallels that ignore the category difference, from ourselves, our human relationships, to Him and our relationship to Him can, then, produce very mistaken notions about the nature of our relationship to Him.
No human parent has created a child in the sense in which God has created you and I and no human parent sustains their child's existence in the way that God sustains your existence and mine at every moment. God's relationship to His creatures extends far, far beyond the boundaries of any human relationship, entailing the exercise of divine prerogatives no human possesses.
God, then, as our Creator and Sustainer, has the right to demand our allegiance and obedience. He has acted, however, in love toward us and approaches us, not as a bullying egomaniac, but as "the Good Shepherd who gives His life for the sheep," (
John 10:11) demonstrating to us great grace, love, mercy and faithfulness.
God has placed us in a world filled with good things: sunsets and sunrises, delicious food, sex, love, beauty, the astonishing glories of the cosmos, humor, majestic mountain vistas, the sweeping power of the ocean, and so on. We enjoy these things to the fullest only as we see them as exhibitions of God's good character, of His power and good will, toward us. But even still, the atheist or demon worshiper may enjoy (to a lesser degree) these things, too. Would a bullying, cruel God allow this to go on? Would a divine tyrant allow the sunshine to warm the just
and the unjust? The sort of God you describe above, then, doesn't at all comport with the God revealed in the Bible or in Creation.
