1 Corinthians 3:5-7

What, after all, is Apollos? And what is Paul? Only servants, through whom you came to believe—as the Lord has assigned to each his task. I planted the seed, Apollos watered it, but God has been making it grow. So neither the one who plants nor the one who waters is anything, but only God, who makes things grow. – 1 Corinthians 3:5-7 New International Version (NIV)
