Ephesians 5:9. “(For the fruit of the Spirit is in all goodness and righteousness and truth:)
Paul pens the command that we walk as children of light, and then inserts this parenthetical truth: We need to walk in light because it is light that produces good fruit. It is the Light of the Spirit that produces all goodness, righteousness, and truth.
God never commands without reason. If He tells us to do something, He does so because it is for our good and His glory, and it will be a testimony and a blessing to those around us. When God speaks in imperatives, we are disobedient to ignore Him. “Walk as children of light” is not just a good idea or a suggestion. It’s a command.
