Where and how does Christian life begin? Some people would say very clearly that it begins when you make a conscious act of faith in Jesus Christ, when you give your life to him, confessing your sins; some would say that it begins when you are baptized – that even as a tiny infant you have begun your Christian life because God has called you and made you his own in baptism.
