The ten commandments where made for the children of Israel as a must obey laws because of what they where passing through then.
The ten commandments where not directly given to these present age...it was only meant to guild us. Back then when you disobey,you get your reward immediately.
The ten commandments where to guild us by will and not a must...it now rest on your onus to live and behave perfectly.
The only commandment given to these present age was "love".
While because if you love someone,you wont kill that person,you wont steal,you wont covet,you wont commit adultery with that person....so if you can love people around you,you will definately love God.
