The Free Will Argument Is Riddled With Insurmountable Problems.
If the Christian god was truly good he wouldn't risk our salvation upon faith amidst a world rife with conflicting religious claims and sects. He would provide an irrefutable and personal revelation via a direct message to each of us and the message would never conflict. A truly loving god would not leave it up to an accident of birth, geography, or what family you're born into to determine whether you will ever believe the right things.
Saying that the Christian god revealing himself would be infringing on our free will is ridiculous. Not only did he reveal himself to various people during the OT he even did so in the NT. If the Christian god is supposed to not favor one over another then it would be unreasonable and unfair for the Christian god to expect anyone to take another person's word for it much less an account told my someone that lives millennia ago and in whom we have no verifiable details about their life much less their motives or honesty in telling these stories.
The Free Will Defense also exonerates the Christian god from answering for the very problems he started. If the Christian god is omniscient, omnipotent, omnisapient, and omnibenevolent then he could very well have placed us in a universe where there would be no sin, evil, or suffering. In fact, an omnibenevolent god wouldn't be able to live with himself unless he did exactly that. If I had a way to prevent or solve suffering I would do it. That means that, I, a mere mortal has more compassion than the Christian god. If I had both the ability and desire to prevent evil and suffering and I didn't do so then I am not a loving or compassionate person.
