1 Corinthians 3:8-11

The one who plants and the one who waters have one purpose, and they will each be rewarded according to their own labour. For we are fellow workers in God’s service; you are God’s field, God’s building. By the grace God has given me, I laid a foundation as a wise builder, and someone else is building on it. But each one should build with care. For no-one can lay any foundation other than the one already laid, which is Jesus Christ.
