What the Bible says about Enlightenment from Keeping God's Commandments
(From Forerunner Commentary)
The commandments of God enlighten. Here, this enlightenment is not so much an environment in which one walks or moves through, but that God's commandments provide understanding or give mental perception of something. What does the mind perceived? Truth, which results in more effective and better judgment in how to conduct one's life.
