An attribute of the virtuous woman is that she lives a consistent life-meaning she acts the same way behind closed doors with only her family watching as she does out in public for anyone to see. 
If we liken the virtuous woman to the bride of Christ, the church, we are reminded that we aren’t to be a people that serve Jesus only inside of the church walls but that we should take His love out into the world. 
The husband praised his virtuous wife just as Jesus will honor your work for him.
