Christians always have hope, no matter how bleak, bad or uncertain the journey, because they know God is always by their side, Pope Francis has said.

In fact, "even crossing parts of the world (that are) wounded, where things are not going well, we are among those who, even there, continue to hope," he said at his weekly general audience in St Peter's Square today.

Just a few days before his visit to Cairo, the Pope continued his series of talks on the nature of Christian hope, saying it is rooted in knowing God will always be present, even to the end of time.
