"Christ declares that his kingdom is explosive in its growth. The kingdom of heaven is like a tiny mustard seed, which explodes in growth and produces massive growth. The kingdom of heaven is like leaven that a woman hides in flour. A tiny lump of leaven leavens the whole loaf. The Gospel is like a contagion that cannot be stopped, and Christ’s rule is irresistible energy. The kingdom of our Lord and of his Christ is unshakable, unstoppable, unquenchable. The graduates we see before us today are evidence of this truth. The powerful seed of the Gospel has born rich fruit, producing a great harvest. As Jesus promised within this very chapter, the powerful seed of the Gospel produces a crop, some a hundredfold, some sixty, some thirty. He who has ears, let him hear....
Just think of this: These graduates are now to be set loose in the world to utter hidden things, to make the name of Jesus famous, to declare the Gospel as public truth and as a message of salvation to be declared to every person and taken to every nation. They are not assigned to conceal, but to reveal. They are not to remain silent, but to speak. They are called to speak truths that so many prophets and righteous men longed to see and did not see it; longed to hear and did not hear it. [Matthew 13:17]"
