Matthew 13:31-32 - The Parable Of The Mustard Seed
31 He presented another parable to them, saying, "The kingdom from heaven is like a mustard seed that a man took and planted in his field. 32 Although it is the smallest of all seeds, when it is fully grown it is larger than the garden plants and becomes a tree, and the birds in the sky come and nest in its branches."
30 He was also saying, "How can we show what the kingdom of God is like, or what parable can we use to describe it? 31 It's like a mustard seed planted in the ground. Although it's the smallest of all the seeds on earth, 32 when it's planted it comes up and becomes larger than all the garden plants. It grows such large branches that the birds in the sky can nest in its shade."
33 With many other parables like these, Jesus kept speaking his message to them according to their ability to understand. 34 He did not tell them anything without using a parable, though he explained everything to his disciples in private.
