"원죄" (original sin) is a concept in Christian theology that refers to the fallen state of human nature inherited from the first humans, 아담 and 이브. According to this belief, their disobedience to 하나님 in the Garden of Eden led to a separation from divine grace, affecting all of humanity. This doctrine suggests that all people are born with a sinful nature, which predisposes them to wrongdoing. It emphasizes the need for redemption, often through the sacrifice of 예수 그리스도, who is believed to offer salvation and restore the relationship between humanity and 하나님.
