1 Corinthians 3:7-9 - For we are God's fellow workers

So neither he who plants nor he who waters is anything, but only God, who makes things grow. The man who plants and the man who waters have one purpose, and each will be rewarded according to his own labor. For we are God's fellow workers; you are God's field, God's building.

So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour. For we are labourers together with God: ye are God's husbandry, ye are God's building.

Commentary

Paul had planted, or started, the church in Corinth; Apollos had watered it-had a significant ministry there after Paul left. But both men were only servants through whom God worked. The ones who plant and water have nothing to boast about because God gives the increase. Only God draws unbelievers to Himself. It is our responsibility to do our job no matter what the results, for God will reward us for our efforts and the quality of our work.
