The Archbishop of Canterbury explains that it was acceptable to occasionally have doubt, and still be a Christian. He added: "The extraordinary thing about being a Christian is that God is faithful even when we're not. When we get into the wrong place he comes alongside us and says, 'Right let's go from here.'"
His remarks were made at an event in Bristol Cathedral in which the Archbishop spoke about why he believes in God and how his
faith in Jesus has transformed his life.
