Don't know who said it first, but my all time favorite 'parenthood' montra :
To the world, you are one person.
To one person, you are the world.
Everyone knows something I don't.
2 Chronicles 7:14
14 if my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land.
