Just a heads up, the negative ETI want to spread a new psyop claiming they made humans so they can later say they are our Gods and that legally we would have to worship them.
As usual, they will try and try to convince everyone so let's stop this psyop in it's tracks. As long as you know how the magician's tricks work, they won't work.
God making us in his image means our Spirit. This body is like a car and is actually the opposite of God's image. Our Spirit deep down inside is perfect and that is the true self. Being "reborn" in Spirit just means realizing that you aren't the body but the Spirit. This leads to salvation since it's like coming out of the insanity of thinking you are just a body. That is the truth.
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.
