Is it true? No.

Jesus said that no one knows, not even he knew when he’d come back.

“But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. Matthew 24:36

“Date fixing,” predicting the day, month and year that Jesus will return, has caused much trouble—church splits, and has even given birth to wayward religions. Just be ready like the virgins in Jesus’ parable, waiting for the Bridegroom (Matthew 25:1-13). Make sure your heart is right before God, that you are truly following Jesus’ teachings, which is what it takes to be his disciple (John 8:31,32), and proclaiming the gospel of the Kingdom of Heaven (Matthew 4:17).

 Is it true? Maybe.

But people have been saying that at the turn of every century since the first one, whenever bad things happened (things have been very bad throughout the centuries), and at the turn of every century. And it didn’t happen. I started hearing this in the 1970’s and found that the idea made people fearful, nervous, unwilling to give themselves to the work of spreading the Kingdom of Heaven—they just wanted a one-way ticket off the earth. What makes our times any more “special” than any other generation’s, especially since our calendar is a fairly “new” one and a western way of counting the days and years? If a person really thinks that the end will come right away, they should be preaching the gospel day and night so that as many people can be saved as possible.
