The sermon concentrates on verses 12b and 13. “If we deny him, he will deny us. If we are faithless, he will remain faithful for he cannot disown himself.” The text itself has always seemed clear to me but I had to re-think the text as I was doing my research and came to a different conclusion. To deny Christ or to be faithless are two actions that we would never want to do and Paul urges us to remain faithful and true, to persevere in our determination to follow Christ. So many around Paul had been ashamed of the gospel and Paul urges us to endure.
