I have heard it said that we don’t need the ten commandments or laws because we are born with natural moral values. The bible says we are sinners from birth and that is because we are not born with natural moral values. They have to be taught to us. We have to be given rules and laws in order to gain these values.
Psalm 51:5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
Psalm 58:3 The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies.
Proverbs 22:15 Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.
I remember when my kids were very little, we never taught our children to lie, cheat, or steal. However, we caught them lying and even stealing. Their conscience knew it was wrong because we had told them it was wrong, that is why they tried to hide it, but if moral values are natural to us at birth we would have never had those conversations. If murder wasn’t illegal I’m sure many more people would be out there releasing their anger right now. People that wouldn’t normally do it because it is illegal.
