There's a couple of bits about mustard in the New Testament - Jesus says if you have faith the size of a mustard seed (ie, very small) you can move mountains (but if I pray right now to move Everest, it probably won't happen because God knows I'm just doing it to prove myself to all you mob); and Jesus also describes the Kingdom of God like a mustard seed, because it starts off small and then grows to be the biggest tree around (in first-century Palestine it was one of the biggest, anyway).

Thanks to all for thinking about this for me =]
