1. I used to be hard headed and still am. It's a nature we're born with because when we finally say YES to God He'll use it in the kingdom for His glory.
2. None of us are perfect and none of us were perfect as teenagers. (Even the extra holy ones.) Some were more focused than others, sure. But some of us were just as lost and bull headed as our teen(s).
BUT even if you were obedient throughout your childhood...
Even if you managed to obey EVERYTHING your parents told you to do.
If you NEVER talked back or had even an angry thought toward a parent. (yeah right/eyeroll) If you managed to live your entire childhood without one ounce of disobedience, The fact that you were born into sin and shapen in iniquity means that from the moment you entered into this world, you came here already on your way straight to hell. So before you open your mouth and rip your baby a new one, shut up and pray.
3. Sometimes you want to SAY SOMETHING to that little fart but God won't let you. Well, maybe the reason God won't let you say anything TO YOUR CHILD is because you haven't said enough TO HIM, ABOUT your child.
