Charles Spurgeon Commentary 1 Corinthians 3:5-9

"What then is Apollos? and what is Paul? Ministers through whom ye believed; and each as the Lord gave to him. I planted, Apollos watered; but God gave the increase. So then neither is he that planteth anything, neither he that watereth; but God that giveth the increase. Now he that planteth and he that watereth are one: but each shall receive his own reward according to his own labor. For we are God`s fellow-workers: ye are God`s husbandry, God`s building." — 1 Corinthians 3:5-9 (ASV)

Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? I have planted, Apollos watered; but God gave the increase. 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.

You are God's tilled ground. Then the apostle works out the same thought under another image, turning from agriculture to architecture.
