God is Light
How does that relate to you when “God is light”? Comparing to “God is Light”, people may more easily understand “God is Love”. “God is Love” is more than a theory or religious practice. The wisdom and goodness of God’s Love is fully communicated through our Lord Jesus Christ. How will you respond to this amazing Love and Grace?
But you may also ask, “What does it mean that God is light?” How can you see and understand that “God is light”? Does this light refer to a physical or spiritual aspect?
Light is a common metaphor in the Bible. Proverbs 4:18 symbolizes righteousness as the morning sun. Philippians 2:15 likens God’s children, who are blameless and pure, to shining stars in the sky. Jesus used light as a picture of good works: “Let your light shine before others, that they may see your good deeds” (Matthew 5:16). Psalm 76:4 says of God, “You are radiant with light.”
God is light sets up a natural contrast with darkness. If light is a metaphor for righteousness and goodness, then darkness signifies evil and sin. First John 1:6 says, “If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth.” Verse 5 says, “God is light; in him there is no darkness at all.” Note that we are not told that God is a light but that He is light. Light is part of His essence, as is love (1 John 4:8).
The message is that God is completely, unreservedly, absolutely holy, with no admixture of sin, no taint of iniquity, and no hint of injustice. If we do not have the light, we do not know God. Those who know God, who walk with Him, are of the light, and walk in the light. They are made partakers of God’s divine nature “having escaped the corruption in the world caused by evil desires” (2 Peter 1:4).
God is light, and so is His Son. Jesus said, “I am the light of the world. Whoever follows me will never walk in darkness but will have the light of life” (John 8:12). To walk is to make progress. Therefore, we can infer from this verse that Christians are meant to grow in holiness and to mature in faith as they follow Jesus.
The above answers to the question about “God is Light” match very well to the first paragraph of John 1: “In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.”
This same Word is the Word spoken by God to create the universe and, specifically, the light in the first day of creation in Genesis. “And God said, “Let there be light,” and there was light.” The most amazing thing that happened in this universe is the same Creator and Great God came to this small Earth as a human being through incarnation! He started His human life as a small baby born in Bethlehem about 2,000 years ago. Just as John 1:14 declares: “The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth.”
