The Ten Commandments

As I was reading the Chapter 20 of the Exodus, I read about the Ten Commandments. The Ten Commandments are the ten basic rules all people should follow in order to go to heaven. This rules were given by God to Moses. So Moses told the people the Ten Commandments (there were only 9 shown):
1. "3) Thou shalt have no other gods before me.
2. 7)Thou shalt not take the name of the Lord thy God in vain; for the Lord will not hold him guiltless that taketh his name in vain.
3. 8) Remember the sabbath day, to keep it holy.
4. 12) Honour thy father and thy mother: that thy days may be long upon the land which the Lord thy God giveth thee.
5. 13) Thou shalt not kill.
6. 14) Thou shalt not commit adultery.
7. 15) Thou shalt not steal.
8. 16) Thou shalt not bear false witness against thy neighbour.
9. 17) Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour's. " (Exodus Chapter 20)
These rules were used before and are still used now. But they are applied differently. Before, all of these rules were the law. If anyone broke any of these rules, he or she will have been punished severly. They used to be very strict about every single Commandment. "24) Eye for eye, tooth for tooth, hand for hand, foot for foot, 25)Burning for burning, wound for wound, stripe for stripe." (Exodus Chapter 21). They used take God and his commandments very seriously. But this has changed.
Now, some of these rules are still part of the law, but only a few of them. For example if you kill, you'll go to jail for a very long time, or you'll stay in jail forever, and sometimes depending were you are, you'll be killed. Also, if you steal or commit perjury (16 Thou shalt not bear false witness against thy neighbour.), you'll go to prison. You still get punished for breaking this rules but not as severly as before. I believe that if the punishments were still as they used to, most of the world's population will be dead or without body parts. The punishments before were very harsh, and this is why it is good that now they have changed.
Something else I thought about when I read, was that now, the other commandments are not so important. Because people now see them more as moral ethics instead of rules. Many people don't really care about them because they don't see them as something bad because they are not part of the law. And if they brake any of those rules, no one is going to punish them. Before, if a wife cheated on her husband it was terrible. Adultery was one of the worst things, people saw it as something terrible, and the wife and her lover will be put to death because of it. But now if a wife cheats on her husband, they just get divorced and that's pretty much it. None of them gets punished by the law or anything. I think it is good that now people don't get punished so severly for breaking the law or commiting moral mistakes. But I still think that even though these commandments don't apply to the law, people should take them more seriously.
