The story is that here the Church is in trouble. Someone has planted bad things and what should we do about it? The answer is: it is not our business. The harvest is the Lord’s. He will deal with it at harvest time. Keep sowing the seed.
THE MUSTARD SEED
A few thoughts on the mustard seed: it is the yellow one in the canary seed packet. It is very small but it is not the smallest. The seed for the Sequoia is smaller for example. In Jewish law it was the standard of smallness when considering ritual impurity from bleeding. If you cut yourself shaving, for example, if the cut is bigger than a mustard seed, you are considered ritually unclean. Anything smaller passes the test.
The parable simply means that great things have small beginnings.
