Though this passage is phrased in Christocentric terms, I encourage even non-theists to contemplate the central message, which directly addresses the overall impact of the activism we espouse and the roots of the change we seek. This is not a means to admit defeat, but rather it is a way to acknowledge a realistic perspective and challenge our assumptions in the process.
It helps, now and then, to step back and take a long view.
The kingdom is not only beyond our efforts,
it is even beyond our vision.
We accomplish in our lifetime only a tiny fraction
of the magnificent enterprise that is God's work.
Nothing we do is complete, which is a way of saying
that the kingdom always lies beyond us.
No statement says all that could be said.
No prayer fully expresses our faith.
No confession brings perfection.
No pastoral visit brings wholeness.
No program accomplishes the church's mission.
No set of goals and objectives includes everything.
This is what we are about.
We plant the seeds that one day will grow.
We water seeds already planted,
knowing that they hold future promise.
We lay foundations that will need further development.
We provide yeast that produces far beyond our capabilities.
We cannot do everything, and there is a sense of liberation
in realizing that. This enables us to do something,
and to do it very well. It may be incomplete,
but it is a beginning, a step along the way,
an opportunity for the Lord's grace to enter and do the rest.
We may never see the end results, but that is the difference
between the master builder and the worker.
We are workers, not master builders; ministers, not messiahs.
We are prophets of a future not our own.
