'Sins' in the Bible

Then he said to them again, I am going away and you will be looking for me, but death will overtake you in your sins. It is not possible for you to come where I am going.

For this reason I said to you that death will overtake you in your sins: for if you have not faith that I am he, death will come to you while you are in your sins.

Any to whom you give forgiveness, will be made free from their sins; and any from whom you keep back forgiveness, will still be in their sins.
