In the Gospel today Jesus shows that perfect balance of what is our work and what is not. He describes the kingdom of god with:
it is as if a man were to scatter seed on the land
and would sleep and rise night and day
and the seed would sprout and grow,
he knows not how.
Are we to work for the building up of the kingdom? Yes, but ultimately it's not our creation or even mostly our work. We use phrases like "my church" or "my parish". The truth is that the neither the parish nor the church is mine nor ours. It's God's. We caretake for a few years of decades for some parishioners, but the church is never ours.
The same is true of life in general. My very soul was God's creation.
We collaborate in His project.
How often in our prayer do we get it backwards? We decide what we want and ask him to collaborate in our project. Then we get upset when it doesn't work out.
Perhaps the simple prayer each day is a question to God: What are we going to do today?
