If god can't lie, does that mean he can't do everything?

[Ahriman]

Free will doesn't mean what most people think it means. Nobody (not even God) has absolutely unlimited free will. That's not how it works. You only have the kind of free will that allows you to fulfill your True Will, which varies from individual to individual. Unlike humans', God's True Will is always good.......He only ever does good things. Humans are different. Humans are allowed to do good and evil things.

There is no contradiction between only being able to do good and having free will and no valid reason a god would not make human beings that way.

(Bold) is correct. But that's a special privilege only God is allowed to have. And there is a valid reason God wouldn't make human beings that way. If you had children, and you were raising them, you wouldn't just give them all the same privileges you have, as a parent, would you? Of course not.
