First of all, I’ve known him for about twenty years and know that he knows what the Gospel is and is not.
Frankly, if you told him that the things you listed are the Gospel, he’d probably laught at you.
Second, you’re the one who made the claim, so it’s up to you to show some evidence for it.
So far, despite having been asked several times, you haven’t been able to articulate it.
Please feel free to prove me wrong by answering the question.
Honestly, I’ve shared the Gospel with literally thousands of people and not one of them has ever said that they were turned off by my attitude.
Frankly, I guess I’d rather preach the Gospel faithfully and have what you consider to be a bad attitude (for what, I have no idea), than to not know what the Gospel is, but be convinced that I’m preaching it.
