1 Corinthians 3:8-10; 1 Corinthians 3:20

8 The man who plants and the man who waters have one purpose, and each will be rewarded according to his own labor. 9 For we are God's fellow workers; you are God's field, God's building. 10 By the grace God has given me, I laid a foundation as an expert builder, and someone else is building on it. But each one should be careful how he builds.
20 and again, "The Lord knows that the thoughts of the wise are futile."
