Yes a believing heart is what I mean by faith. Hence a good moral character has faith and believes God is good, Loving and wise. I'm not sure what you mean by a spirit of understanding. Do you mean a person who understands or a person who is willing to understand? The change I am referring to for us, is from a carnal way of thinking to a spiritual way of thinking. Romans 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God. No, when I'm saying her character changed, I am saying she was at first content in her countenance and had want for nothing, even though she was not allowed to eat of the knowledge of good and evil. Then the devil spoke his lies, and as she considered his words her countenance changed and she was no longer content but lusted for the knowledge of good and evil. Satan's words clearly have something to do with that. All of Satan's words are slanderous to God. That's like saying murder is okay if you don't know it's wrong. Whereas I would say, we were already created good without the knowledge of good and evil, and we would never contemplate murdering anyone. But we wouldn't know how to appreciate what that goodness is, because we wouldn't know what evil is in contrast to that goodness. Hence the knowledge of good and evil is the knowledge of what goodness is, in contrast to evil. I think that is most likely true. They had no knowledge of lies.
