The concept of light and dark, and their contrast, are found throughout the pages of Scripture. From the opening verses of Genesis, one finds God speaking light into the void of darkness (Gen. 1:3). Over time, God manifested himself to humanity often using light and fire to indicate his presence. God is often identified with light. Isaiah writes, “The Lord will be your everlasting light, and our God will be your glory” (Isa. 60:19). The psalmist notes, “The Lord is my light and my salvation, whom shall I fear” (Ps. 27:1). God is robed with light (Ps. 104:2) and light dwells with him (Dan. 2:22). John, more explicitly, notes, “God is light, and there is absolutely no darkness in him” (1 John 1:5). While God is light, his presence is not restricted from knowing dark areas. The psalmist pines, “Even the darkness is not dark to you. The night shines like the day; darkness and light are alike to you” (Ps. 139:12). Thus, God’s light and his insight penetrates and overcomes even the darkest of areas.

Jesus picks up on this theme and teaches two profound truths. First, he holds that he is light, saying, “I am the light of the world. Anyone who follows me will never walk in darkness but will have the light of life” (John 8:12). As such, Jesus shows that he embodies God’s revelation and his goodness. Second, Jesus also instructs his followers, noting, “You are the light of the world. A city situated on a hill cannot be hidden” (Matt. 5:14). The disciples were to be evangelists sharing the gospel and spreading the love of God to the world. I used to think that believers are mere reflections of the light of God, much as the moon reflects the light of the sun. While I still think there is some merit to the claim, an understanding of the Spirit’s work in our lives illustrates the idea that the light shines from the inworking of the Spirit in our lives. As such, we are like torches that flame the light of God in the areas where God places us. More on that to come.

What does it mean to say that “God is light?” Obviously, with the emphasis of divine light that has already been noted in Scripture, God’s light must hold some weighty meaning. Concerning the light of God, three things can be said of God’s light.

God’s Light is Revelatory. First, God’s light reveals the truth. God exposes things as they truly are. On the one hand, God’s light reveals the truth about reality. The psalmist notes that God’s truthful direction is a “lamp for my feet and a light on my path” (Ps. 119:105). As such, God provides wise instruction on how to handle life’s most difficult circumstances. In addition, the Spirit of God, or the “Spirit of truth” (John 14:17), sheds his light on the believer by guiding them into the truth (John 16:12-14).

On the other hand, the light of God reveals wrong behaviors by exposing sin. The Spirit also is known to shedding divine light onto individuals by convicting the world about sin, righteousness, and judgment (John 16:8-11). Jesus said that it was for this reason that those who loved evil abhorred the light of God, for they feared that their deeds would be exposed (John 3:20). Ironically, the light of God will eventually expose every deed anyhow, regardless of whether one tries to hide their misdeeds or not.

God’s Light is Relational. God’s light often refers to divine holiness. Worded another way, God’s light reveals that he is the absolute good. As previously noted, this was part of John’s teaching concerning the light of God in his first letter. God’s holiness is viewed by Paul to be an “unapproachable light, whom no one has seen or can see” (1 Tim. 6:16). The unapproachability of God was overcome by the work of Christ on the cross by making people righteous so that they can boldly approach the throne of grace (Heb. 4:16). Because of the work of Christ, people can now shine the light of God in a world of darkness.

God’s Light is Rousing. By rousing, I do not infer the idea of a crowd enamored by a well-performed theatrical play. Rather, the term refers here to the giving of life. The symbol of light often referred to life in contrast to sorrow, adversity, or death (Ellis, NBD, 690). To see God’s light was to live (Job 3:16; Ps. 49:19). To walk in God’s light is to walk in the “light of life” (Ps. 56:24; Job 33:30). Light to the eyes is considered the gift of physical life that God grants to all (Prov. 29:13). As such, it is unsurprising that God’s presence is shown to be an effervescent, radiant light (Rev. 1:9-20; 4:1-11).

The concept of God’s light did not stem from Hellenistic thought but was deeply rooted in Judaism. Such is evidenced in the usages of light in the OT and the Qumran texts (e.g., War of the Sons of Light and the Sons of Darkness). Could it be that some sages of philosophy (i.e., Socrates and Plato) and the writers of the inspired Word both caught a glimpse of God’s transcendent light? Even if such is true, the full revelation of God would be found in his Word.

Nonetheless, I come now to the application of the article. I am sure you have heard the song This Little Light of Mine. The lyrics read, “This little light of mine, I’m gonna let it shine. This little light of mine, I’m gonna let it shine. This little light of mine, I’m gonna let it shine. Let it shine, let it shine, let it shine.” God often places us in dark situations and circumstances so that our light will shine brighter. Our world is becoming a dark place to reside. Not only do we have a pandemic, but we also have national uprisings and cities in complete turmoil. Why has God decided to place us in this time and place? While there have certainly been darker times in world history, God has placed us in such a time as this to allow our lights to shine for God’s glory. Things may not be easy for a while. However, the light of God filling us and guiding us will truly be a “lamp unto our feet and a light unto our paths” (Ps. 119:105).

No matter what you may face today, this week, this month, or the remainder of this year; decide today that you will let the light of God shine through your life. Don’t be overcome by the darkness of the world, but rather overcome the darkness with the light of God’s glory. Then, we can all sing together, “Won’t let Satan blow it out, I’m gonna let it shine. Won’t let Satan blow it out, I’m gonna let it shine. Won’t let Satan blow it out, I’m gonna let it shine. Let it shine, let it shine, let it shine!”
