Mk 4:26-34

Jesus said to the crowds:
“This is how it is with the kingdom of God;
it is as if a man were to scatter seed on the land
and would sleep and rise night and day
and through it all the seed would sprout and grow,
he knows not how.
Of its own accord the land fruit,
first the blade, then the ear, then the full grain in the ear.
And when the grain is ripe, he wields the sickle at once,
for the harvest has come.”
He said,
“To what shall we compare the kingdom of God,
or what parable can we use for it?
It is like a mustard seed that, when it is sown in the ground,
is the smallest of all the seeds on the earth.
But once it is sown, it springs up and becomes the largest of plants
and puts forth large branches,
so that the birds of the sky can dwell in its shade.”
With many such parables
he spoke the word to them as they were able to understand it.
Without parables he did not speak to them,
but to his own disciples he explained everything in private.
Bishop Barron:
Friends, today’s Gospel compares the kingdom of God to a mustard seed that when “it is sown, it springs up and becomes the largest of plants.” It seems to be a law of the spiritual life that God wants good things to start small and grow over time.
We’re tempted to say, “You’re God. Just get on with it. Do it!” But why would God work the way he does? We might attempt a few explanations. It is a commonplace of the Bible that God rejoices in our cooperation. He wants to involve us, through freedom, intelligence, and creativity, in what he is doing. And so he plants seeds, and he wants us to cultivate them.
Consider what God said to St. Francis: “Francis, rebuild my Church.” God could have rebuilt his Church without Francis, but he wanted him to get involved.
When things start small, they can fly under the radar while they gain strength and heft and seriousness. Also, those involved can be tested and tried. Suppose you want to do something great in the life of the Church and you pray and God gives you massively what you want. You might not be ready, and your project will peter out. So be patient and embrace the small invitations.
