True Christian friends will build each other up emotionally, spiritually, and physically. Friends like to be together simply because it feels good . We receive strength , encouragement, and love. We talk, we cry, we listen. But at times we also have to say the difficult things our dearest friend needs to hear. Yet, because of the shared trust and acceptance, we are the one person who can impact our friend's heart, for we know how to deliver the hard message with truth and grace. I believe this is what Proverbs 27:17 means when it says, "As iron sharpens iron, so one man sharpens another."
