Only Jesus can give this kind of life and it's the kind we want to teach to our children. Life is a gift given to us by God. He is the author as well as originator and has the right to set the rules. That is what the sixth commandment is all about as it prohibits murder. NIV says you shall not murder, King James version says thou shalt not kill.
Murder is a more accurate translation from the Hebrew.
Before I go any further, let me tell you what this is not talking about. This is not talking about animal rights and breaking into laboratories and setting the rats free. This is not talking about capital punishment being state sanctioned. Murder that only multiplies the violence of our society. On the contrary, the Bible makes a strong case for capital punishment through Israel's law code.
