Earlier this year, as we commemorated the 80th anniversary of D-Day, the Queen and I had the enormous privilege of meeting, once again, the remarkable veterans of that very special generation, who gave of themselves so courageously on behalf of us all.
Listening to these once-young servicemen and women touched us deeply as they spoke of their comrades, drawn from across the Commonwealth, who never returned and who now rest peacefully where they made the ultimate sacrifice.
Their example of service and selflessness continues to inspire across the generations.
During previous commemorations, we were able to console ourselves with the thought that these tragic events seldom happen in the modern era.
But on this Christmas Day, we cannot help but think of those for whom the devastating effects of conflict in the Middle East, in Central Europe, in Africa and elsewhere, pose a daily threat to so many people's lives and livelihoods.
We also think of the humanitarian organizations working tirelessly to bring vital relief.
After all, the Gospels speak so vividly of conflict and teach the values with which we can overcome it.
The example that Jesus gave us is timeless and universal.
It is to enter the world of those who suffer, to make a difference to their lives, and so bring hope where there is despair.
As the famous Christmas carol, 'Once in Royal David's City' reminds us, "Our Saviour holy came down to Earth from heaven", lived among "the poor and mean and lowly", and transformed the lives of those he met, through God's "redeeming love".
