It’s a long read and worth it, because it beautifully explores the theme.
But these are two quotes that summarize the main though:
God: Why, the idea that I could possibly have created you without free will [is a fallacy]! You acted as if this were a genuine possibility, and wondered why I did not choose it! It never occurred to you that a sentient being without free will is no more conceivable than a physical object which exerts no gravitational attraction. (There is, incidentally, more analogy than you realize between a physical object exerting gravitational attraction and a sentient being exerting free will!) Can you honestly even imagine a conscious being without free will? What on earth could it be like?
And
Don’t you see that the so-called “laws of nature” are nothing more than a description of how in fact you and other beings do act? They are merely a description of how you act, not a prescription of of how you should act, not a power or force which compels or determines your acts. To be valid a law of nature must take into account how in fact you do act, or, if you like, how you choose to act.
