The yellow circle on the sign says, "The Bible Guarantees It"!
Tuesday night at Bible study we had a good discussion about this false prophecy. Among other things, it was mentioned that many of the signs that will precede the coming of Christ have not yet been fulfilled. The point was also made that our calling is to watch, and pray, and work. The Lord will take care of the rest.
"But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father. ... For the Son of man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch" (Mark 13:32, 34).
