Light

Light in Scripture is both a created reality and a recurring image for God's own being, presence, and saving action. The text says the first creative word of God was "Let there be light" (Genesis 1:3), and that the sun and moon are appointed as lights for seasons and days (Genesis 1:14–16); light is thus part of the made world, not a divine attribute in itself. Yet the same texts speak of God as light without qualification: "Yahweh is my light and my salvation" (Psalm 27:1), and the promise that the sun and moon will no longer serve as light because "Yahweh will be your everlasting light" (Isaiah 60:19). The Hebrew word behind these statements is or, the ordinary noun for light, and the Greek of the New Testament is phos; in both, the term carries its everyday sense while being applied to God himself.

The New Testament most often uses light as a moral and revelatory category, set over against darkness. The text says "the light has come into the world, and men loved the darkness rather than the light, for their works were evil" (John 3:19), and Jesus says of himself, "I am the light of the world" (John 8:12). Paul describes his commission as opening eyes "that they may turn from darkness to light and from the power of Satan to God" (Acts 26:18), and grounds the light of the gospel in God's first command: the God who said light shine out of darkness "has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ" (2 Corinthians 4:6). James calls God "the Father of lights, with whom can be no variation nor turning shadow" (James 1:17); one way to read this is as an allusion to the heavenly luminaries, whose shifting shadows contrast with the constancy of the God who made them.

Light also names the identity and conduct of those who belong to God. The text says, "you were once darkness, but are now light in the Lord. Walk as children of light" (Ephesians 5:8), with the call to awake because "Christ will shine on you" (Ephesians 5:14). Peter describes a people "called out of darkness into his marvelous light" (1 Peter 2:9), and John ties walking "in the light as he is in the light" to mutual fellowship and to the cleansing blood of Jesus (1 John 1:7). Prophecy itself is compared to "a lamp shining in a dark place, until the day dawns and the morning star arises in your hearts" (2 Peter 1:19), so that light can mean the present guidance of Scripture as well as the final dawn.

Christian traditions have read the term with real differences of emphasis. In Eastern Orthodox teaching, the light of texts such as the transfiguration and the promise that God will be his people's everlasting light is identified with the uncreated divine energies, a light of God's own life rather than a created effect, a reading embodied in the language of liturgy and in the theology of the divine light. Much Western theology, Catholic and Protestant alike, has treated light primarily as a metaphor for revelation and moral order: Augustine's account of divine illumination and the Reformation's insistence that God's word is the lamp by which the church is guided both belong here, and both stress that the light is received rather than possessed. Pentecostal and charismatic readings often connect the indwelling light with present experience of the Spirit, while more historically minded readings keep the emphasis on the gospel message and the ethical walk that the epistles describe. The texts themselves hold creation, revelation, holiness, and future glory together without resolving the term into a single technical sense.
