This passage brings up some interesting things that are of relevance to Christ followers. Paul the writer tells the believers in Colossae that he and others are praying for them that they will live in obedience, that they will grow spiritually and that there will be spiritual fruit produced for the glory of God.
So this entails there be evidence in the life of a Christ follower that he/she is really a Christ follower (that there has been a new birth). This is a paradox and a point of contention in many cases. This is only the case because the new birth into the family of God is receive by rote repetition of a canned prayer. Simple repetition of words without genuine authenticity results in nothing but the passing of air.
It would seem that there are a number of people that are not authentic Christ followers who are in churches, not producing spiritual fruit in their lives because they have not been born again. This causes many people to start saying that a believer does not need to produce spiritual evidence in their life, evidence of a new birth into the family of God. This is a dangerous thought and seems to be left over from the time of the Reformation. Salvation is by grace through faith in Jesus Christ’s death, burial, and resurrection. But, there should be outward evidence of this inward spiritual transformation.
Does there seem to be a difference, does there seem to be progress in your life?
