The American poet Robert Frost wrote: “The afternoon knows what the morning never suspected.” I know what he means. I remember turning 40 and realising that my life was probably half way through; today my elder son is 40 and I look back with amazement at what has happened, what choices we all made, what experiences we shared, what relationships we forged.

Frankly, I think we did a good job: despite being born in Cheltenham and living around the country, he has always been a passionate Liverpool fan. What more could I want?

Well, quite a lot actually. To go back to Robert Frost, I remember looking at a baby and realising the responsibility asleep in my arms. And the uncertainty about what might lie ahead of him - not just in the choices we and he would make as he grew up, but also what might happen in the world that couldn’t be controlled but would shape or constrain those choices.

While celebrating Christmas over the last few days I was conscious of the fact that the baby of Bethlehem grew up into an argumentative boy who clearly learned by debating and questioning. The boy grew into the man who learned his trade before hitting the political arena and eventually getting nailed to a cross.

Growing up - and letting our own children grow up - is a nerve wracking business. We can’t control what will happen to the children we love. We do our best … and face our failures … recognising that this is a pattern they might also one day repeat. But, if uncertainty is the name of the game, then society has to give all children the best start, the best example, the best opportunity.

Which means what? Especially as no child can grow in isolation from other children, whatever their background.

Well, along with guest editor Raheem Sterling this morning, we might start with education and opportunity. The Germans have two words for it: ‘Erziehung’ has to do with nurture and learning, ‘Ausbildung’ is all about training for a skill. And both are valuable. Of course, at the heart of both lies a person - the roots of whom need to be watered by more than mere information or ‘knowledge’ - if they are to develop wisdom and character.

And this means enabling young minds to roam widely, dig deeply, face unwelcome challenges and hard questions. As Aristotle noted: “It is the mark of an educated mind to be able to entertain a thought without accepting it.”

Or, as the Book of Proverbs puts it: “Happy are those who find wisdom, and those who get understanding.”
