Paul’s desire is that the Colossians will bear fruit in every good work. When we think of good works, we picture an individual performing acts of kindness and charity. Yet while these are important activities, they are not what Paul has in mind. Instead we should see good works as the opposite of works of the flesh. Good works refers to every holy activity of a believer.
Paul expects God to ensure that all those who are pleasing Jesus by their lifestyles will continue producing spiritual fruit in all they do. Perhaps we can illustrate it in this way. A believer is like an apple tree and the branches and twigs are his good works (big and small). On every branch and twig there should be apples. Sadly we only have apples on some of them. Paul knew that some of the Colossians were not what they should be. Yet he prayed that they would all become fruit bearers.
How can we produce fruit in every good work? Imagine that you are doing it for Jesus. When reacting to a situation, ask yourself, What would Jesus say or do, and how would he say or do it? If we are doing something by ourselves, ask how would we do it if Jesus was standing beside us. If we are wondering how to pass the time, ask yourself in what ways Jesus would spend time. Of course, the best way to do something fruitful is usually to do one thing at a time, and to do it for Jesus.
