“Our children are God’s greatest gift to us. No matter how they are packaged, this truth does not change. Be grateful; love, honor, and cherish them. If your child is not perfect or what you hoped for, God has not punished you for past deeds. He has given you an opportunity that you may not yet understand. Make the most of the situation, for you are in it for a purpose, and there are rewards, that you never imagined possible.” — author unknown
