Christ said that before He returns there would only be one sign to herald His coming.
Matthew 24:37 But as the days of Noah were, so shall also the coming of the Son of man be.
Theologians have interpreted this to mean that the conditions of the world would be the same as those that were before the Flood. This is indicated by the following verse.
Matthew 24:38,39 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ark, 39 And knew [understood] not until the flood came, and took them all away; so shall also the coming of the Son of man be.
And the world does seem to have gotten into the same state now, maybe it is even worse. When discussing this a few days ago with a friend he suggested something that really struck a chord with me.
On July 7, 2016 the Ark Encounter1 opened for visitors in Williamstown, Kentucky (see Fig.1), an actual-size replica of Noah’s Ark (157 m, 510 ft long). It is located inland, far from water, and used by Answers in Genesis to educate people about the size of the Ark and other issues related to the Earth destroying global flood in Noah’s day,2 that resulted the death of all air-breathing land dwelling as well as all flying creatures. But most importantly it meant the death of all humans except for those 8 that were on the Ark, Noah, his wife, Noah’s 3 sons Shem, Ham and Japheth and their wives.
