I have just come inside from saying shacharit, the morning prayers, in the garden. The last of the snowdrops, the crocuses, the early daffodils; that faint late February smell of pre-spring buds and promise: my heart gives thanks for you.

There’s nothing I want more than to pass to my children, to all children, a world of such wonder and multifarious beauty. The longing to do so has become my passion and, increasingly often, my frustration.

Perhaps it seems odd to focus on pastoral trivia in a week of political drama. I haven’t had my head in the sand. On Monday I had to facilitate what became an angry and aggressive evening on the impact of anti-Semitism. On Tuesday I worried for my French colleagues as there took place in France hate and counter-hate demonstrations. Last night I spent with the Community Security Trust.

I worry for Jewish, and not just for Jewish, MPs. I worry for anyone who, in this rising tide of populism, puts their head above the parapet in the name of humanity, truth and compassion. And I’m sure we have to be out there with them.

Meanwhile the government and opposition in this country are caught in the blinding intricacies of Brexit, bringing most other business to a virtual halt. Elsewhere, Presidents Putin, Trump and Bolsonaro are not currently leading their countries, or the world, in inspiring directions.

Yet all the while the earth itself is suffering, as report after report, on soil impoverishment, insect depletion, falling biodiversity and habitat loss makes so clear that it’s hard to bear reading them. If this continues, with land and food loss, we will see refugees from environmental disaster, from whole territories become uninhabitable, in numbers we had not imagined before.

In these frightening times, when the future of humanity is at stake, we need leadership which faces the real issues in energy, agriculture and transport policy, and in economic and social justice. We need a leadership with integrity, honesty, humility and imagination. We need leaders who can help us turn fear of the future, and the anger and frustration it engenders, into a vision for the future which inspires and enables us to work together, British, European, Jewish, Muslim, whoever we are. I expect this is what many current leaders aspire to be and do. Perhaps they need not just our support and encouragement, but also our indignation.

This brings me back to the garden. Nicky – my wife – has become a galanthophile, a lover of rare and unusual varieties of snowdrop. When, as we stared at two virtually indistinguishable flowers, I asked her why she cared so much about the minute differences in petal and pattern, she said, ‘Because they make me notice’. I’ve been thinking about that answer ever since.

The garden, the park, the birds, make me notice. The refugees we’ve hosted, the homeless I’ve met and the people I’ve encountered who look after the homeless, make me notice. Noticing makes me care and caring makes me passionate. This helps me find others, individuals, organisations, leaders in thought and action, who know more. They are my teachers and my inspiration, in Britain, Israel, wherever they are.

What matters most is not blaming other leaders but supporting and becoming leaders in the issue about which we care.

Judaism teaches me to love this earth, cherish this creation, care about people, seek understanding, support those who are weak, live by my values.

The sight of the snowdrops reminded me of that this morning.
