(Ephesians 4:17-19) So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking.  They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts.  Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, and they are full of greed.

Isn’t it interesting that the world around the Ephesian Christians sounds like the present-day world?  Think about the words “futility of their thinking”.  In our times there seems to be frequent opportunity to form the question, “what were they thinking”?  As you read through today’s scripture, I think you’ll find that the Apostle Paul clarifies why the thinking of the world of today is illogical. 

Paul wanted the Ephesians to be careful to not fall into the darkened understanding and separation from the life of God that was going on all around them.  The world has definitely not changed regarding its spiritual condition.  Therefore, Paul’s warning is as significant for God’s children today, as it was in his day.

The common statement, “we are in the world, but not of the world,”² is relevant.  We are members of God’s eternal kingdom, and no longer of this fallen world.  We are the redeemed, so therefore, we need to allow the Holy Spirit to lead us into living as Jesus taught us.  Jesus said that we are salt and light to the world around us.  So not living as the unsaved world is paramount.  We cannot be salt and light for our neighbors, if we are living the same life as those who live in darkness.
