This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all. (1 John 1:5)
As finite creatures we have trouble getting our arms around absolute knowledge. Even with the places or subjects that we are most familiar with, we often kick over another rock to discover something new.
This is not the case with God. He knows everything and everyone perfectly. He is the infinite God. His knowledge is complete. He is never learning or growing. Instead, he is utterly sufficient in his absolute and infinite perfection.
This is why such statements as John’s above are so astounding. God’s declares that he is light. This metaphor in the Scriptures refers to God’s purity or holiness as well as his knowledge. The assertion is that God is perfectly pure without any defect or blemish.
What makes this all the more astounding is that God himself is infinite. In other words, the infinite God has plumbed the depths of his infinite character, surveyed it, and concluded with credibility of his divine character: I am perfectly light! In the mansion of God’s character there is not a single room, closet, or hallway of iniquity—every room is bright light and a fragrance, a boquet of holiness!
As a result, believers are to walk in the light (1 John 1.5, 7). We are to press into his character and reflect it into the world around us. As we are doing this we are reminded that it is the holy and perfect sacrifice of Jesus (1 Jn. 1.7) that enables this. It is his holy blood offered for us that brings holiness to unholy people. As you can see it was God’s holiness (light) that determines the need for salvation as well as the nature of our new lives in Christ. Praise be to God that he has worked this in and through the Lord Jesus Christ!
Rejoice in and respond to this holy God–the God who is light!
