c. The harvest has come: Just as a field’s crop may be unnoticed when first planted, but can’t be missed when mature, so it is with the Kingdom of God. It has small beginnings, and its root may be small, but when God develops the work it cannot be missed. i. This is the glory of Jesus’ work in us. It was prophetically said of Him, a bruised reed He will not break, and smoking flax He will not quench (Isaiah 42:3). Jesus takes something as small and insignificant as a seed, buries it, and makes it rise up to something glorious. So, we should never despise the day of small things! (Zechariah 4:10)

ALL praise to The Lord Jesus!!! How glorious His  Kingdom that He can make so great a Kingdom from such miniscule materials! 

HE  REALLY IS NOT LIMITED BY THE “MATERIALS” (that is, YOU & ME!!) HE  WORKS WITH! 

.. and so, my dogged feelings of not "being enough" are gloriously thrown into the garbage bin!! :D 

and he goes on =)

a. It grows up and becomes greater than all herbs, and shoots out large branches: Some regard this as a beautiful picture of the church growing so large that it provides refuge for all of the world. But this mustard seed plant has grown into a monstrosity, and it harbors birds - who in the parables are emissaries of Satan, according to the foundational parable of the soils (Mark 4:13).

i. “The growth of the kingdom will not result in the conversion of the world. In fact, some of the growth will give opportunity for Satan to get in and go to work!” (Wiersbe)

b. Jesus, in considering the growth of the work of God, reminds us that size and status are not necessarily benefits. There has never been a great curse upon the world than corrupt Christianity, of the form of godliness without the power.
