The Expansive Nature of the Kingdom of Heaven

Our Lord taught in both the parable of the mustard seed and the leaven in Matthew 13 that the kingdom of heaven is expansive by nature. Yet as we look upon the world around us, we can plainly see both false doctrine and sin expanding like leaven, but it seems that the kingdom of heaven is shrinking, not expanding. In what sense does God's kingdom expand on this earth, and how does it expand? In this message we seek the answers to these questions.
