The fact of the matter is no one except God in heaven knows when the end of the world will happen. The infallible Word of God makes this very clear. The Bible also makes it very clear that there will be an increase of false teachers. Harold Camping is an example. His belief about knowing when the Rapture would occur is a clear misrepresentation of God’s Word. It is just a publicity stunt if you ask me.
“But false prophets also arose among the people, just as there will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction upon themselves.” 2 Peter 2:1
Jesus said, “Truly I say to you, this generation will not pass away until all these things take place. Heaven and earth will pass away, but My words will not pass away. But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone.” Matthew 24:34-36
