What are the marks of being a genuine believer? What are the signs that we truly love God? We often think in terms of the fruit of the Holy Spirit (Gal 5:22-24), and this would be correct. But there are other, less obvious marks, which are still valid nonetheless. Namely, how do we respond to correction regarding our sin? This is what Paul will be dealing with as he approaches the end of his letter, from 2 Corinthians 13:5-7.
