I agree with most everything discussed in this section. Without God, what reason does man have not to lie, steal, cheat, and murder? I know that I personally am capable of being quite sneaky and manipulative. I could totally get away with several types of theft, without any physical consequence.
What keeps me in line is God and his laws. A basic moral code is essential to society… without it… well, see Selco for details on what things will look like.
