Several months ago, a good friend sent me a message that was meant to be helpful. He offered me an unsolicited suggestion related to a hobby of mine that I wasn't really looking for outside input on. I politely thanked him, but also felt a little annoyed with his suggestion. A few hours later, after I had time to digest his message and research his suggestion, I realized he was right. I sent him a second message with a more genuine thank you than the first.
Why is it so difficult for us to receive outside help and recommendations? Could it be that once we make up our mind about something we find the task of remaining teachable too tiresome? Could it be that we sometimes idolize our own opinions and preferences? Could it be that we've developed a hardened heart?
What do we do when we receive instruction, opinion, or correction? Do we hear the messenger or do we "kill" the messenger? What does Scripture teach about this dilemma?
