I am not good at memorizing, but passages like this one make me want to be. Paul tells this congregation that has competing loyalties to quit quarreling and to end their jealousy. "After all," he says, "who's really doing the accomplishing?"
We each have a part to play in accomplishing the work that God has given us to do, but we shouldn't ever think that the work is ours entirely. Neither should we think that we deserve all the credit.
As Paul puts it, "For we are God's servants, working together; you are God's field, God's building." I'm remembering when I was a child, that when riding through the country, my grandmother would look out at the fields and comment on whether the cotton or corn was looking good for that time of year. Now, I'm imagining someone observing a local congregation, God's field, and noticing how it was doing.
Only God gives the growth, but we church people sure can provide some weeds.
