Proverbs calls us to be upright, to walk in righteousness. It contains the call of holy living just like the New Testament does. One of the difficulties of holiness is that it requires a discerning and engaged mind. Jesus was not just concerned with our souls. Perhaps that is why when He quoted the law He felt free to add the need for our minds.
(Matthew 22:37 KJV) Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.What that has in common with this verse is that while certain things such as adultery and lying are always wrong, there are many acts which will be sinful or righteous depending on the context and company. Christmas is also the season of Jewish Hanukkah. You are not being a hypocrite if you do not serve ham when you have a Jewish friend over for dinner. It is called being considerate and discerning. It might be a sin to serve it at that time.
So? There is a time to eat and a time to drink. There is a time to abstain from both or either. Live upright. That puts your mind at the top in control of the feet at the bottom.
