The beautiful book of Revelation is the Lord's own "emergency preparedness handbook." It was given to us two thousand years ago as a fire drill for the end of time, so that no one would have to be caught unaware. No one knows exactly when God will say, "Enough!" as he did in Noah's generation when he saw how great man's wickedness had become on the earth, being only evil all the time. His heart was so grieved he said, "I will wipe mankind off the face of the earth." And he did. Noah was the only man on the planet who knew great waters were about to flood the entire Earth. He and his family survived that first apocalypse because he acted on the warning. The Revelation is God's warning for this and every generation. He did not hide the warning of the end of time in a sacred vault. Every detail of the end is available in the last book of the Holy Bible. We only have to study it to show ourselves approved.
