God has spoken and acted in Jesus Christ. He has said something. He has done something. This means that Christianity is not just pious talk. It is neither a collection of religious ideas nor a catalogue of rules. It is a ‘gospel’ (i.e. good news) - in Paul’s words ‘the gospel of God ... concerning his Son ... Jesus Christ our Lord’.2 It is not primarily an invitation to man to do anything; it is supremely a declaration of what God has done in Christ for human beings like ourselves.
