This is the script of this morning's Pause for Thought on BBC Radio 2's Chris Evans Show with Sara Cox and guests: Gabby Logan, Josh Gad and Lianne LaHavas. (There are ten of Liane's song titles and a reference to the work of Josh Gad and Gabby Logan for good measure.)

Well, I might as well announce it to the nation: my daughter has just had a baby. He's called Joseph and he's tiny and I love him. He's got a head of dark hair and he left me tongue-tied.

I nearly cried when I held him. I did get teary when I saw my daughter and son-in-law in the hospital and felt the unstoppable love that gets behind the emotional defences that often protect us from hurt. No room for doubt here: love can be elusive, but it's impossible to forget and you can never get enough of it.

Which bears thinking about when you watch the news and feel the misery. Yet, in the midnight of pain it's the daylight of wonderful love that keeps breaking through, catching us unawares and reminding us of our fragility and challenging our selfishness.

There are people who think that love is something merely romantic or soppy. I mean, it is great when it is romantic; but, love is much more than that. I would give my life for my kids and grandchildren (Joseph completes the hat-trick) because love goes deeper than anything else. When I did my daughter's wedding in Croydon some years ago, I remember looking at the gifts wrapped in paper covered in love hearts. I asked if this is really the best we can do as an icon of love. The icon of love I turn to is a man with his arms stretched out on a cross, embracing a world that couldn't handle him and demonstrating that love is never cheap. Christian faith is born of blood – costly love … as, of course, is the love that leads to a painful labour and childbirth.

I guess my question to myself this morning is this: Is your love big enough? Or do I settle for an imitation that costs less or is more convenient? Anyone who has loved will also bear the scars – because love can sometimes hurt.

Anyway, with a nod to the Beatles, “you can't buy me love”; but, with a nod to Josh Gad, our hearts do not need to be frozen. And that, Gabby, is the final score.
