I want to know the answer to the following question:
When verse was the third mention?
All the background I'm provided with is that "The third and final New Testament reference to the term is in 1 Peter 4:16, which exhorts believers: "Yet if [any man suffer] as a Christian, let him not be ashamed; but let him glorify God on this behalf."". Is that enough to answer the question?
Answer: yes
