1 Corinthians 4:18-5:2
18 Some are arrogant, as though I were not coming to you. 19 But I will come to you soon, if the Lord wills, and I will find out not the talk of these arrogant people but their power. 20 For the kingdom of God does not consist in talk but in power.
5:1 It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father’s wife. 2 And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you.
