I was reading the parables one day and reading these two, I remembered the Holy Spirit and wondered if Jesus could be giving an example of how sanctification happens. If I'm wrong, then you will have to forgive my ignorance. ;)
"And He said the kingdom of God is as if a man should scatter seed on the ground. He sleeps and rises night and day, and the seed sprouts and grows; he knows not how. The earth produces by itself, first the blade, then the ear, then the full grain in the ear. but when the grain is ripe, at once he puts in the sickle, because the harvest has come." This reminds me of what Paul said in Colossians chapter 1:
"We always thank God, the Father of our Lord Jesus Christ, when we pray for you, since we heard of your faith in Christ Jesus and of the love that you have for all the saints, because of the hope laid up for you in heaven. Of this you have heard before in the word of the truth, the gospel, which has come to you, as indeed in the whole world it is bearing fruit and growing—as it also does among you, since the day you heard it and understood the grace of God in truth, just as you learned it from Epaphras our beloved fellow servant. He is a faithful minister of Christ on your behalf."
Also, in Matthew 13: "The kingdom of heaven is like leaven that a woman took and hid in three measures of flour, till it was all leavened."
