1 Corinthians 4:17-19

4:17 For this reason, I have sent Timothy to you, who is my dear and faithful son in the Lord. He will remind you of my ways in Christ, as I teach them everywhere in every church. 4:18 Some have become arrogant, as if I were not coming to you. 4:19 But I will come to you soon, if the Lord is willing, and I will find out not only the talk of these arrogant people, but also their power.
