Right and wrong are two opposite things. When we disobey the law (human law), there is corresponding punishments/ or punishment to it. When you obey traffic rules, the police will caution you and will issue you ticket with corresponding amount of money as fine.
The same is true with the law of Moses. The 10 commandment states
1. You shall have no other gods before me.
2. You shall not make for yourself any carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children to the third and fourth generations of those who hate me, but showing mercy to thousands, to those who love Me and keep My commandments.
3. You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain.
4. Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your manservant, nor your maidservant, nor your cattle, nor your stranger who is within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it.
5. Honor your father and your mother, that your days may be long upon the land which the Lord your God is giving you.
6. You shall not murder.
7. You shall not commit adultery.
8. You shall not steal.
9. You shall not bear false witness against your neighbor.
10. You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, nor his manservant, nor his maidservant, nor his ox, nor his donkey, nor anything that is your neighbor’s.”
"The above 10 commandments need no explanation. They mean exactly what they are saying. It’s quite amazing how many of these commandments are being broken on a regular basis, even by Christians themselves. If you look very closely at each of these commandments, they really do cover a broad spectrum as to what God is expecting from each one of us.
These 10 commandments are good, basic, moral laws that will help keep us out of trouble with ourselves, family, friends, and neighbors. God knows what is best for all of us and He simply wants all of us to stay out of trouble in order that we may be able to live in peace and harmony with one another.
The fact that God would go so far as to have these basic 10 commandments manifested on a stone tablet really tells me they are very important, and that each Christian should know what they are and do their best to abide by them with the help of the Holy Spirit." - Bible-knowledge.com
