Here's what our Holy Father had to say in his encyclical on hope:
Only when the future is certain as a positive reality does it become possible to live the present as well. So now we can say: Christianity was not only "good news" - the communication of a hitherto unknown content. In our language we would say: the Christian message was not only "informative" but "performative." That means: the Gospel is not merely a communication of things that can be known - it is one that makes things happen and is life-changing. The dark door of time, of the future, has been thrown open. The one who has hope lives differently; the one who hopes has been granted the gift of a new life.
