Who do you think Paul is, anyway? Or Apollos, for that matter? Servants, both of us—servants who waited on you as you gradually learned to entrust your lives to our mutual Master. We each carried out our servant assignment. I planted the seed, Apollos watered the plants, but God made you grow. It’s not the one who plants or the one who waters who is at the center of this process but God, who makes things grow. Planting and watering are menial servant jobs at minimum wages. What makes them worth doing is the God we are serving. You happen to be God’s field in which we are working.
Or, to put it another way, you are God’s house. Using the gift God gave me as a good architect, I designed blueprints; Apollos is putting up the walls. Let each carpenter who comes on the job take care to build on the foundation! Remember, there is only one foundation, the one already laid: Jesus Christ. Take particular care in picking out your building materials. Eventually there is going to be an inspection. If you use cheap or inferior materials, you’ll be found out. The inspection will be thorough and rigorous. You won’t get by with a thing. If your work passes inspection, fine; if it doesn’t, your part of the building will be torn out and started over. But you won’t be torn out; you’ll survive—but just barely.
