There is a difference between punishment and the natural consequences of sin. Because of what Jesus did on the cross, there is no more punishment for sin. That doesn't mean that there aren't consequences, but it means God's not bringing them into your life. It means He's the source of everything good in your life, not all the evil.

The Gospel is the incredibly good news that our right standing with God isn't based on our performance but rather our faith in what Jesus did for us.
