Murder has been wrong since the beginning of creation.
When Cain murdered his brother Abel,
murdering was wrong. (Genesis 4:8)
When violence filled the entire pre-flood world,
murdering was wrong. (Genesis 6:11)
When the flood was finally over
God made clear to Noah that
murdering was still wrong.
However, it was not until after the Flood that Scripture explicitly states (for the first time) what penalty should be imposed upon murderers. God said to Noah:
Surely I will require your lifeblood; from every beast I will require it. And from every man, from every man’s brother I will require the life of man.Murder is such a disgusting sin that most unconverted people even recognize it as a crime. When one person murders another person, most people naturally conclude that the murderer deserves to be punished. According to Scripture, the punishment that a murderer deserves is death. Why does a murderer deserve death? Genesis 9:6-7 provides an answer. God said to Noah:
Whoever sheds man’s blood,
By man his blood shall be shed
For in the image of GodAt creation, man was given a certain purpose: to be fruitful and multiply, fill the earth, and subdue it (Genesis 1:28). Whenever anyone murders another person, they are going directly against this purpose.
He made man.
As for you, be fruitful and multiply;
Populate the earth abundantly and multiply in it.
People are also made in the image of God, which means that all people have inherent worth. People are not animals; people have souls. They have thoughts and emotions. Therefore, if you kill another person, you have taken away the life of something higher than a mere creature. You have taken the life of a being made in the image of God!
The penalty that should be imposed upon any person who murders another person is death. For anyone who might question the "legality" giving a person the death penalty for murdering, God (once and for all) settled the issue in Genesis 9:6, Whoever sheds man’s blood, by man his blood shall be shed.
