Maybe its because I'm a Londoner...
Just read this:
"Every Christian denomination should be on the alert for London; it is the first duty of Londoners themselves, but believers in the country are also concerned in the right condition of the metropolis. London is in some respects the very heart of the world; it influences every land, its vice is a plague to the whole human race, and its religion may be a balm to the remotest lands. London must be the Lord's; we long to see it set as a gem in the diadem of Jesus, as the Kohinoor among his crown jewels."

Amen! These are Spurgeon's words from 1875.
But how we need that to be our prayer today...
