If godly behavior is part of our true nature, then godly behavior is not within the scope of free will, as we are bound to behave godly (at least eventually).
If godly behavior is not part of our true nature, then godly behavior is within the scope of free will, although then the question is why and how we would choose to behave in a manner other than that which is in line with our nature (any behavior that is contrary to our nature, we would experience as suffering).
If our true nature is empty or chaotic, then it is not clear how we can choose in any sensible way, so in that case, it would be absurd to talk about free will.
If we posit that currently, we are in a state where we are out of touch with our true nature (and so acting by what we consider our intution won't necessarily result in godly behavior), we need to have some kind of reason to believe and recognize that this or that particular behavior (as proposed by various religions) is godly while another is not.
But the idea that currently, we are in a state where we are out of touch with our true nature, also places us at the mercy of anything and anyone.
