"Iron sharpens iron" is a phrase rooted in scripture. It is something we must do to become more like Christ. Luke 24 explores our need to be sharpened as Christians and what it means to be an Iron Sharpener. 

We aren't called to live life alone, and we aren't cut out to be alone as Christians. We need people in our lives to sharpen us and push us closer to Christ. As others pour into us, we also have the chance to be Iron Sharpeners to others. 

Don't allow yourself to lose your edge as a Christian. We are useless to Christ if we walk around like a dull knife.
