"Repeat a lie often enough and it becomes the truth."
The internet is split in attributing this quote to Lenin, Hitler, and Goebbels.
The uncertainty, ironically, does not stop the attributions from being repeated - until they become accepted truth.
There is a theological lie that gets repeated often and, thus, taken for truth, and it drives crazy every time I hear it: "Jesus taught more about hell than about heaven".
You will find this sentence in the mouths of way too many preachers, from the unknown to the famous, but I don't believe I have ever heard anyone even attempt to quantify it with hard data.
It wouldn't be hard to do. There are plenty of tools online these days to help - you wouldn't even have to reread the four Gospels with a highlighter in hand.
In fact, all it takes is a little thought and reflection and you would instantly see the impossibility of Jesus teaching more about hell than heaven.
If you DID quantify it, you would find - like this guy - that Jesus spoke on heaven at least five times as much as on hell.
I'm not sure why people get so invested in promoting a hell of eternal torture that they have to resort to obvious lies to bolster their position.
Satan, being the Father of Lies, undoubtedly approves.
