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.
1 Corinthians 8:7
8:7 But this knowledge is not shared by all. And some, by being accustomed to idols in former times, eat this food as an idol sacrifice, and their conscience, because it is weak, is defiled.
