1 Corinthians 4:19-20: "But I will come to you soon, if the Lord wills, and I shall find out, not the words of those who are arrogant but their power. For the kingdom of God does not consist in words but in power".
Paraphrase: "I am coming to see you and I am going to test you. And let me make it clear to you - I am not interested in your words but in power. Any fool can get up and speak. The question is, is there power in the man's speech? What does it accomplish? What does it lead to?".
