Matthew 24:38-39 says, For as in the days that were before the flood they were eating and drinking, marrying and given in marriage, until the day that Noe entered the ark, and knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
The days of Noah were characterized by gross immorality but the Lord mentions only that they were eating and drinking. Is there anything wrong with eating and drinking? No, we are told that whatever we do, whether we eat or drink, or whatever we do, we are to do all to the glory of God.
The problem was, the people in Noah’s day wasn’t eating and drinking to the glory of God. In fact, they were living as though God did not exist. I see this all the time in the day in which we live. People go out to dinner and they eat and drink and never thank God for their meal. Even today, we act as though God doesn’t exist. Some people are like my dogs, they just start right in!
