This prediction was not supported by the Bible. People that think they can predict the Rapture have huge unwarranted self-importance issues.
Matthew 24:5 (NKJV) "For many will come in My name, saying, 'I am the Christ,' and will deceive many."
Matthew 24:36 (NKJV) "But of that day and hour no one knows, not even the angels of Heaven, but My Father only."
People who claim to know are blasphemers and do not represent His Word.
