What animal could Noah not trust?
The Cheetah. Ha! Ha!
God has breathed life into all Scripture. It is useful for teaching us what is true. It is useful for correcting our mistakes. It is useful for making our lives whole again. It is useful for training us to do what is right. By using Scripture, the servant of God can be completely prepared to do every good thing. -2 Timothy 3:16-17 NIRV
Training a child to do what is right isn't an easy task. Choose one thing to focus on this week. That may be being polite, truthful, generous or any of a million other things we hope our kids learn. Now, take that one thing and work it into every day. For instance, if you choose to work on manners, make sure your child says "thank you" when you give him/her anything. Make sure your child says "please" before giving him/her what they've asked for.
Not only do you make sure your child says these things, but praise them each time they do. If you spend a whole week focusing on this, I think you will love what you see next week without your prompting!
