@MontereyJack,
You are ignorant. Adam and Eve introduced sin into the world because they ate from the tree in the Garden of Eden they weren't supposed to eat from. Every human being who has ever born after them was born into sin because of that.
People in the world, the Bible says, are in spiritual darkness, because of Adam and Eve- they are
seperated from God.
People know it is wrong to do things like kill and steal but I am not talking about that. Secular people sin and not know they are sinning. They don't see anything wrong with what they do.
The BIble calls the Devil the prince of the world and if people aren't serving God then they are serving the Devil, the Enemy - they are slaves to sin.
The Devil has them in bondage.
Jesus came to do on the cross and redeem people from sin so that man wouldn't have to die in their sins.
