Jesus believed it to be true.
If He believed that is good enough reason for me to do likewise.
Yep, Jesus believed it:
‘Just as it was in the days of Noah, so also will it be in the days of the Son of Man. People were eating, drinking, marrying and being given in marriage up to the day Noah entered the Ark. Then the Flood came and destroyed them all.’ (Luke 17:26–27)
Who are we to argue.
