What you say is correct if by error you mean sin and disobeying God. Except I wouldn't say we learn to be good through trial and error because we have the knowledge of good and evil written on our hearts. But if you mean it in sense of spiritual growth where sinning is inevitable, I agree.

We choose sin and evil (which leads to death) through our own free will because of our fallen nature, so it's not a matter of knowledge and the mind (gnosis) but of the heart, namely rebelliousness and pride - the things that led to the fall in the first place. We must return to the pre-fall state and that's only possible through communion with Christ (theosis) since He took Adam's sin upon Himself with His sacrifice and defeated death.

We choose sin and evil (which leads to death) through our own free will because of our fallen nature, so it's not a matter of knowledge (gnosis) but of morality, namely rebelliousness and pride - the things that led to the fall in the first place.
