John 1

I decided to start reading the Epistle of John in the Bible. I just finished reading the Book of Mormon, focusing on the prophesies/life/mission/teachings of Christ and so I thought it would be good to follow that up with reading about his life in the Bible. I picked John because it is one of my favorite books in the New Testament.

Today, I was impressed with the thought that Christ came down to take away the "sin" of the world. It struck me that sin was singular. Does anyone know why sin is singular?

Sorry for the brevity of this post, I am late for school.
