Not when you make such a public declaration of knowing when the world ends and the Bible clearly tells you that no one knows that except the Father. And he’s done it once before with the same result. What’s the definition of insanity?
There are various clinical definitions of insanity.
The "repeating an action but expecting a different result" vernacular definition is a nonstarter: people routinely repeat actions that are initially futile (like drilling for oil) and are not actually considered insane.
People routinely talk their way out of supposed dilemmas: "no man knows the day or the hour" isn't the same as "no man will ever know the day or the hour" they will argue.
Many congregations and groups are built on similar hairsplitting.
