Matthew 13:31 - Clarke's commentary and critical notes on the Bible

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: The kingdom of heaven is like to a grain of mustard seed - This parable is a representation of the progress of the Gospel in the world; and of the growth of grace in the soul. That grace which leads the soul to the fullness of glory may begin, and often does, in a single good desire - a wish to escape hell, or a desire to enjoy God in heaven.
