We try every day in some way to influence our kids: food choices, cleanliness, saying "nice" things, telling them things we learned as children.
So many times are my words falling on deaf ears? I've become a master of non-verbals, which could sometimes knock me off my chair...rolling eyes, deep breaths followed by "Mooooom", or walking ahead of me anytime we're in public so people won't recognize we're together. Yes, teen parenting calls on many different skill sets you learn thru hard experience or wonderful, sharing friends who have already been there.
Just when I'm at that point of collapsing, I'm sent an encouraging friend sharing good things she's heard or seen in my child--or a decision she makes for the right reason...then I am given confirmation her ears were working! Paraphrasing from your words, "2nd Cup of Coffee", "We notice (like God notices) when they "listen" to what we place on their hearts."
So....I'll continue to pray she understands God to the depths of her soul, seeking His input in every decision; especially when I'm not there to remind her--then He'll have to deal with her rolling eyes! ~:)
