#DailyProverbs 23:9: "Don't try to talk sense to a fool; he can't appreciate it."
I love the twosidedness of this scripture. We tend to believe that when WE speak, OTHERS will listen and be transformed. Stop. You will likely never change someone that obstinately refuses to change on that principal alone.
Just like when others speak to you, trying to teach you something... you refuse to listen to them.
