I do hope that some folk, when visiting me in my (still to be organised!) study, will look at the object on the wall, and ask why there are no hands for the clock, but Praying Hands in the centre! The answer, of course, will be that it is always time to pray!
He (Lewis) explained: "We must not picture destiny as a film unrolling for the most part on its own, but in which our prayers are sometimes allowed to insert additional items. On the contrary, what the film displays to us as it unrolls already contains the results of our prayers and of all our other acts.
"There is no question whether an event has happened because of your prayer. When the event you prayed for occurs your prayer has always contributed to it. When the opposite event occurs your prayer has never been ignored; it has been considered and refused, for your ultimate good and the good of the whole universe."
