“And you, having been dead in your the trespasses and sins, in which you once walked according to the fashion of this world, according to the ruler of the authority of the air, the spirit which now works in the sons of disobedience.”
As we have noted several times already, this letter is not written to people in general, but to believers in the church. Paul’s words once again reinforce that notion when he speaks of the sins “in which you once walked.” One of the most telling marks of a Christian is that the way they conduct their life is different than the way the world functions. This includes, but extends beyond just “good morals” and reflects a change in purpose. Those who live according to the world will live to serve themselves; those who are Christians will live to serve Christ first and foremost.
There is a principle about which I have spoken for years, and that has to do with the way priorities are spoken of in western culture. For example, people most commonly say things like: “this is my first priority, this is my second…” It is my belief that we are not designed to compartmentalize our lives in that fashion. In fact, I would submit that we are only ever able to have one priority in life and that everything we do flows out of that priority. Further, I think that there are ultimately but two options: God or self.
If God is your priority in life, you will still be a good employee, a good parent, a good neighbor, and a good citizen, but you will be all of these things because you recognize them to be aspects of the way you serve and honor God. If self is your priority, then you still may be a good employee, a good parent, a good neighbor, and a good citizen, but only insofar as those things serve your needs. The world says, “be true to yourself.” The Bible says, “be true to God.” which will it be?
Paul is writing of the change that takes place in the life of the believer. “Once we served self, now we serve God,” is the heart of his message here. Once we pursued the fashion of this world; now we pursue righteousness, holiness, and Truth. Once we served the devil, either explicitly or implicitly; now we serve Christ. Once we were numbered amongst the “sons of disobedience;” now we are called “Children of God.”
