SO WHAT IS THE UNFORGIVABLE SIN? Like most YouTube videos nowadays, which waste too much of my time by not addressing the clickbait in their titles until the very end of lengthy clips, this one follows that same pattern. However, I've now developed a habit of simply skipping to the end of videos right off the bat. Consequently, I have no idea what makes up the main body of this video's content, but do appreciate the insights shared during the last couple of minutes.
Fellow Christians, please stop bumping such foolish threads to the top of the list. "Do not speak to a fool, for he will despise the wisdom of your words." Prov "Do not speak to a fool, for you will not find wisdom on his lips." Prov "Stone is heavy and sand a burden, but provocation by a fool is heavier than both." Prov "A man that is a heretic after the first and second admonition, reject." Titus. God tells us to avoid such people. Do people actually like wasting their time? There is no profit from arguing with such people.
