Why giving children [or anyone else] "consequences" doesn't work.

Mother to young son: 

"If you don't pick up your toys, you'll lose a privelege.  I warned you that there would be consequences."

Translate: 

"If you don't meet my expectations, pain will follow:  I will either remove something from you, or do something to you." 

Most of us were brought up under a compliance model:  "Just get kids to behave.  Give them 'consequences' if they don't meet your expectations."

Natural consequences:
Yes, there are natural outcomes to our choices:  Relationships don't do well where there isn't mutual respect, including from child to parent.  However, the carrot and stick [reward and punishment] model doesn't work.  [Note:  rewarding a child, in order to get good behavior, has also shown to short-change genuine transformation in the long-run.]  In fact, research indicates that if you insist on punishing [or rewarding] kids for their behavior, you'll end up with a worse kid in the long run.  Remember, true transformation is measured in years, not minutes.

Giving "warnings" and "consequences" didn't even work for God:

"If after all this you will not listen to me, I will punish you for your sins..."  [Leviticus 26:18]

"...as your sins deserve."  [Leviticus 26: 21]

"They will pay for their sins because they rejected my laws..."  [Leviticus 26:43]

Did God's warnings that consequences would follow produce heart-change in his people?  No.  They still went ahead and did what he warned them not to. Why?  Pressure to comply - and the threat of consequences that accompany that - will never produce the actual change we really want for our kids.  Being intrinsically [self-motivated] to love well is far superior to being threatened into acting like you care about others.

So what's the alternative?
Connection.  Put the heart first.  Here's another post I wrote that gives you some concrete suggestions:  "Parenting Where the Heart Comes First."
