"No one knows, however, when that day and hour will come -

neither the angels in heaven nor the Son;

the Father alone knows.

The coming of the Son of Man will be like what happened

in the time of Noah.

In the days before the flood people ate and drank,

men and women married, up to the very day

Noah went into the boat;

yet they did not realize what was happening

until the flood came and swept them all away.

That is how it will be when the Son of Man comes.

Matthew 24:36-39
