What does the Bible say about the mustard seed parable?

In the parable of the mustard seed, found in Matthew 13, Jesus uses the imagery of a tiny seed that becomes a large tree to represent how the Kingdom of Heaven, though seemingly insignificant at first, ultimately grows into a vast and encompassing reality. This speaks to the nature of God's kingdom and the work of Christ, who may have seemed despised and small in human eyes, yet carries within Him the fullness of salvation and hope for sinners. It teaches us to look beyond mere appearances and cherish the profound work that God is doing through seemingly small beginnings.
