What does the parable of the mustard seed mean?
Matthew 13:31-32 tells the parable of the mustard seed: The kingdom of heaven is like a mustard seed, which a man took and planted in his field. Though it is the smallest of all your seeds, yet when it grows, it is the largest of garden plants and becomes a tree, so that the birds of the air come and perch in its branches. Using parables, Jesus related truth through intriguing stories with familiar settings. Our grasp of this parable hinges upon a correct understanding of its key elements: the sower, the mustard seed, the great tree which grew from it, and the birds which perched on its branches. The first two elements are easily understood.
