The greeting in Titus 1:1-4, at the start of Paul’s letter,  is a preview and an overview: the truth about Jesus accords with godliness. For the Christian, belief in Jesus ought to be reflected in our behaviour as we seek to be more like him. But our good works don’t save us – Jesus is the saviour. At Christmas, we celebrate God’s grace shown to us and have the privilege of reflecting that grace to others.
