Proverbs 1:8 (MSG)
Pay close attention, friend, to what your father tells you; never forget what you learned at your mother's knee.
I'm pretty sure there have been entire books written on this one sentence. Powerful stuff!
I have a very close relationship with my parents, so for me this one is easy. I respect them and soak up what they tell me. The older I get, the more I have come to appreciate their opinions and feelings on issues. As I am a parent now, I realize that this is something that cannot be forced. It is a choice whether we hear and apply what our parents (or parent figures) share with us. I have chosen in the past and will continue to earnestly listen to their guidance.
