What does the Bible say about God being light?

In 1 John 1:5, the Apostle John declares, 'This then is the message which we have heard of him and declare unto you, that God is light, and in him is no darkness at all.' This profound statement establishes God as the ultimate source of purity and holiness. Light represents the absence of sin, which is essential for fellowship with God. Since God is light, His nature is perfectly pure, and everything He does reflects His holiness. Furthermore, light signifies knowledge and truth, as demonstrated in Psalm 119:105, where God’s Word is described as a lamp unto our feet, guiding us in truth and righteousness.
