Maybe there are some genuinely divine people who are simply born as godlike, divine beings who never commit any sin. But usually, if you do something wrong, make mistakes, or sin, you then may come to realize that you were doing something wrong, and then learn from that mistake. Being born perfect as a no sinner is really unrelatable imho
However if Jesus = God then it would make sense for him to never sin, because we should assume that God is perfect in every way and would not sin
All that being said, all of these speculations are pointless since our understanding of godhood or godliness can surely not accurately be expressed in words, which again, makes me smarter than YoungHoon Kim (because he is making these unverifiable claims) and would make me the smartest person in the world who has ever lived
