[Prayer] is probably the most distinctive Christian contribution to the political process. We can vote, act, speak out and protest in much the same way as our non-Christian neighbours. But we can do something they can never do: Pray to the God of the universe. Your most important contribution to the political process happens not when you step into the ballot box, or when you write a letter to your MP, or when you take part in a peaceful protest march. It happens on your knees.
