They were eating and drinking and marrying and being given in marriage, until the day when Noah entered the ark, and the flood came and destroyed them all.
Luke 17:27 ESV
The days of Noah were pretty ordinary. People were just doing ordinary things. Yes, they might have been especially evil in those days, but there was something mundane about their rebellion against God.
Whether someone’s evil or righteous, they’re going to be eating or drinking. Even evildoers marry and give in marriage. But on the day Noah entered the ark, all that came to an abrupt end.
Jesus wasn’t just telling antidiluvian stories for the sake of it. He was illustrating what was going to happen on the day of His return. Just as the flood destroyed the ancient world, so fire will destroy this present world, before it’s recreated.
Christ’s return is going to take many by surprise. People will just be getting on with their ordinary, workaday lives, and the end will suddenly come. We need to be ready for the return of the King.
“Father God, may we prepare and be ready for the return of Your Son. May we renounce evil and trust in You, to Your praise and glory, amen”
