There are words about sin in the ten commandments,such as Rape, steal, kill.
In my opinion, this is the curse.The curse comes from the tree of knowledge of good and evil.let me ask you a question,How do you know what is rape,steal,kill? where those knowledge comes from?If there were no flaws in the Old Testament, I don't think there would be such words to describe sin in ten commandments.So we have the New Testament, the New Testament depicts beautiful words Instead of sin.From now, it's a real blessing.
From the perspective of God as a whole, complete full law is blessing.
