Baker’s Evangelical Dictionary of Biblical Theology informs us that light literally expels darkness. When we examine the word “light” in the Bible, we'll see a contrast of light and darkness in the Old and New Testaments. The literal contrast is between metaphysical good and evil, God and evil forces, believers and unbelievers. The Bible entertains no thought that darkness is equal in power to God’s light. The Light of God is always shining, which means, as children of light (Eph. 5:8), we should always have the victory in Christ Jesus.
