"physical force; they maintain their dominion by war; but the founder of the new kingdom is the Prince of Peace. The Holy Spirit represents worldly kingdoms under the symbol of fierce beasts of prey; but Christ is “the Lamb of God, which taketh away the sin of the world.” John 1:29 .

Birds flitted from twig to twig, and sang amid the leafy foliage. Yet the seed from which sprang this giant plant was among the least of all seeds.

And how rapid was its growth, how widespread its influence! When Christ spoke this parable, there were only a few Galilean peasants to represent the new kingdom.

EGW directly references and explains the parable of the mustard seed from Matthew 13:31-32.
