"They are blind in that they fail to see what they should see. They have become so shortsighted that they have forgotten the most important reality of all. Peter observed that those who are not practicing these virtues have forgotten their baptism and their forgiveness of sins. In other words, they are not living as forgiven sinners. They are behaving like unconverted people. If members of the church are living immoral lives, they bear witness that forgiveness means little to them. Those who treasure being forgiven live in a way that pleases God." —Thomas R. Schreiner
