Whether you’re a Christian or not, chances are you hear the word “sin” a lot, and might not really know what it means. I was raised in a Christian church and have always been interested in Christian theology, and have just recently started to form an understanding of what sin is. I think a lot of the confusion comes from the fact that we only use one word regularly for “sin” but it has many different meanings.
I believe all humans have intrinsic value because we are all made in the image of God; Imago Dei. Even if you don’t believe that, I’m sure you believe that there is something that connects us all and gives us value. Otherwise, murder should be legal.
