The Parable of the Mustard Seed, one of Christ’s shortest allegories, typically receives scant attention in our scripture study. But since it appears in each of the synoptic gospels, perhaps it’s worth more careful consideration.
Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.
Matt. 13:31–32 (KVJ).
