LIGHT
(a) In addition to references to physical light as existing independently of the sun, and emanating after the sun as a great light, this term is used in the Scriptures in a very prominent way in a moral sense.
The light of God is his word by which he reveals himself, and by which he not only reveals the dangers that exist in this scene, but also acts as a lamp to show the true path (Ps. 119: 105).
The psalmist asks Jehovah to lift up upon him the light of his countenance (Ps. 4:6), and declared that Jehovah himself was his light (Ps. 27:1). Just as natural light gives vigor and health to the body, so the light of God gives joy and strength to the soul.
“God is light,” and the Lord Jesus came to earth as the true light that illuminates every man. He not only manifested by his presence all the evil in the world and the false pretensions of the leaders of Israel, but “the life was the light of men” (John 1:4; 8:12). .
Christians are “light in the Lord” (Eph. 5:8), and are exhorted to walk as “children of light” (1 Thes. 5:5). In the midst of darkness they must shine as lights in the world (Phil. 2:15).
A serious responsibility rests upon them, since they must not tarnish the brilliance that should characterize them as having in their hearts the light of the glory of the Lord. If the light in the Christian turns into darkness by not walking in the reality of the path of Christ, how great is the darkness! (Matt. 6:23).
It has been said that light very appropriately describes God. Light, invisible itself, manifests everything. Christians, as has already been noted, are “light in the Lord”, and therefore manifest the fruitless works of the flesh.
On the other hand, it is not said of them what is said only of God, that they are love, because love is the sovereign source of activity in God. God is light (1 Jn. 1:5) and God is love (1 Jn. 4:8). The Christian is light in the Lord, and we are exhorted to love one another, as He has loved us (John 15:12).
