I have linked to this website for you to check it out. This website gives a holistic view of law and grace and insights into each of the Ten Commandments.
I quote from this website : The stone tablets containing the ten commandments are an inseparable part of the cross. The tablets reveal God's holiness and expose mankind's sinfulness. The cross represents Jesus' life that was given in order to bring reconciliation between God and man. Without the law, there would be no need for the cross. Without the cross, the law would lead to despair and death. Both together reveal the beautiful purpose of God for His greatest treasure - People!
