is God possibly subtle?

The atheistic argument from Divine Hiddeness:

Assume the following:

1. God exists
2. God made man in his image
3. Necessarily, if God made man in his image, then it’s God’s duty to make Himself known to the creatures whom bear his image in any circumstance whatever.
4. God didn’t make himself known to me.
5. God doesn’t exist (since 3 entails the necessity of God making myself known to me if he exists, and I don’t know he exists, then necessarily God cannot exist).

The rebuttal to the argument from Divine Hiddeness: the argument from Divine Subtlety, which finds premise three suspect:

Surely premise 3. is too strong to be prima facie true. Imagine a possible world where God is subtle, where he only makes Himself known to those who have the eyes to see, ears to hear, and a pure heart. Imagine that God is such that only those who are willing to discern His existence are able to see that he exists. If such a world is even possible then premise 3 is necessarily false.

So is it possible that God is subtle? There’s no contradiction in the above description, so it’s at least logically possible. But is it metaphysically possible? Maybe despite the logical possibility of it being true, maybe it must be ruled out for metaphysical reasons. But what would such a reason look like?

Maybe the following:

6. God so loves his creatures that He would never not let them know that He exists.

Is 6 blatantly obvious? No, for maybe God has reasons for being subtle, like

7. God so loves His creatures He wouldn’t force them to believe He exists unless they wanted to believe.

Is 7 possible true? Surely, for

8. Love never moves the beloved if the beloved must be moved against the beloved’s will.

8 seems obviously true, and I’d invite anyone to find an exception. Since 8 is true, then 6 and 3 are false, and so the argument from Divine Hiddeness collapses.
