When you say "sin" what is the definition thereof (for I would like to see if it matches with others definitions here).
IMHO-I think that the 10 Commandments was meant to SHOW us what sin is to God. And I am SO very grateful to be freed from law.
Matthew 22:37-40 New International Version (NIV)
37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind. 40 All the Law and the Prophets hang on these two commandments.”
