I recall years ago a little book came out called, 88 Reasons the Rapture Will Be in '88. I never read the book, 'cuz I knew it wasn't going to be in '88. But, Dude, how does it feel to be wrong 88 times?! Yet the date-setters continue: 2000, 2012, etc. "Family Radio" guy announced Big Day three different times! I think he should have retired after the first miss! So what's my problem?
It's that the Church has like zero credibility with the unbelievers after all the foolish talk and predictions that don't come true. They're laughing at us: The Simpsons did a parody of Left Behind! The Scripture says, "My Name is blasphemed among the Gentiles through you." (Isaiah 52 & Romans 2) Newsflash folks: unbelievers can read the Bible too, and they can see it doesn't say what you're preachin'.
Don't you realize you can't possibly predict the day of the Lord's return? For Jesus said, "The Son of Man comes at a time when you think not". So any date you pick is automatically wrong because it's not a day you think not! Some of you, that went right over your head. If you say He's coming next Christmas, then next Christmas is a time you think so, not a time you think not.
Moreover, Christ told the Apostles, "It is not for you to know the times or the seasons" concerning the end & the Second Coming. If it ain't for us to know, then the Holy Spirit ain't telling, and you're only guessing. I don't care how many trips you've made to the Holy Land, or how many years you've studied Greek! Nobody knows, OK? Here's a tip: next time you think you got it figured out when the Rapture happens, just keep it to yourself, huh? Then when nothing happens, no one will label you a false prophet.
It's like these guys who think they've ID'd the AntiChrist cuz they tallied up the letters in the dude's name and it works out to 666 with a little creative math. (FYI: no one was ever named DCLXVI) Well, your Bible says the Son of Perdition will be revealed in his time. So it won't be revealed until then, and trust me, your puny mind ain't twisted enough to figure out Satan's plan for global domination. Plus, he's had a 5,000 year head start on you.
Bottom line: God "...frustrates the tokens of the liars, and makes diviners mad; that turns wise men backwards, and makes their knowledge foolish." (Isaiash 44:25) Those who presume to figure out hidden knowledge just make themselves, the Church, and God look bad. You don't know, and can't know, so just say you don't know. You'll look a whole lot smarter. Pardon my attitude.
