For the kingdom of God is not in word, but in power.
All Commentaries on 1 Corinthians 4:20 Go To 1 Corinthians 4
John Chrysostom
AD 407
“Actions speak louder than words,” says Paul. “If those Corinthians who are now arrogant want to prove something, let them show me when I come whether they can do the same miracles I can do. I do not want to find them hiding behind a wall of words, for that sort of thing means nothing to me.”
