He told them another parable; “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.
Jesus is a wonderful story-teller. He used parables to help us visualize biblical concepts. In this scripture He reminds us that a mustard seed is about as small a start as it gets. Yet, after it grows it not only becomes one of the biggest garden plants; it actually becomes a tree. What was once only a small seed becomes a full-grown tree, fulfilling its purpose in life.
