New Defender's Study Bible Notes
1:5 God is light. Since God is light, dwelling in light (I Timothy 6:16), He did not have to “create” light, but simply say: “Light, be!” (Genesis 1:3). On the other hand, He did create darkness (Isaiah 45:7) as the initial state of the unformed and uninhabited earth (Genesis 1:2). When light appeared to disperse the darkness, it could thereby become a model of the shining of spiritual light into a soul born in the darkness of innate sin (II Corinthians 4:6). Physically, God is the light of shining glory; intellectually, He is the light of truth; and morally He is the light of holiness. He is also the light of life (John 1:4) and of true guidance (John 8:12).
