"Chapter 5—“Like a Grain of Mustard Seed” This chapter is based on Matthew 13:31, 32 ; Mark 4:30-32 ; Luke 13:18, 19 . In the multitude that listened to Christ's teaching there were many Pharisees. These noted contemptuously how few of His hearers acknowledged Him as the Messiah. And they questioned with themselves how this unpretending teacher could exalt Israel to universal dominion. Without riches, power, or honor, how was He to establish the new kingdom? Christ read their thoughts and answered them: COL 76"
"And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it? It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth: But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it."
Ellen White directly references Mark 4:30-32 in this passage.
