“A fairly standard minimal interpretation of Matt 24:38 emphasizes the thinking of man was upon daily carnal living void of spiritual life with God.”
Interestingly, what is mentioned “eating and drinking, marrying and giving in marriage” are all good things when God is in the picture. The problem comes when God is not factored in - one ends up with gluttony and drunkenness, trying to become one flesh without the commitment of marriage, so-called “gay marriages”, etc.
I believe the emphasis is on daily living and our happiness by our own provision, as opposed to reliance on God’s Provision.
