How do we know that God is light?

1 John 1:5 asserts, '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 declaration helps us understand the nature of God's holiness and purity. His light illuminates truth and dispels sin and darkness. Within God, there is no ambiguity or deceit; His character is wholly and completely good. The absence of darkness in God assures us that He is the epitome of holiness, and when we walk in His light, sin cannot abide.
