Why do we go against what God says is for our good?
Human nature rebels against God's prohibitions, just as a child immediately wants the forbidden door. From Eden onward, Satan, God's adversary, urges people to do what God forbids and to neglect what God commands, so humanity turns opposite God's best and suffers heartache.
Les teaches that we are no different from a little child told not to go through a door; as soon as the parent turns away, the child wants to look behind it and go through. In the same way, when God says, 'Thou shalt not steal,' or 'Thou shalt not commit adultery,' human nature says, 'I'm going to try it.' From the very onset in the Garden of Eden, when Satan approached Adam and Eve and sin came on the scene, Satan became God's greatest adversary. Les explains that everything God says it is best for us not to do, Satan says do it; everything God says it is best for us to do, Satan says don't do it, and the world adds, 'Why should you?' So from the human side we always find ourselves going the opposite direction from what God has told the human race is for our own good. That is why there is so much heartache: people have gone contrary to what God set down as our best. God knows what is best, and no society can survive by totally going contrary to these Ten Commandments, because they are basic.
