Whoever sheds the blood of man, by man shall his blood be shed; for in the image of God has God made man. (Genesis 9:6, niv)
Here God explains why murder is so wrong: To kill a person is to kill one made in God’s image.
Because all human beings are made in God’s image, all people possess the qualities that distinguish them from animals: morality, reason, creativity, and self-worth.
When we interact with others, we are interacting with beings made by God, beings to whom God offers eternal life. God wants us to recognize his image in all people.
