The eye, in Scripture, is the organ of physical sight and the most-used metaphor for the inward seeing of perception, desire, judgment, and faith. The single eye fills the body with light (Matthew 6:22); the evil eye plunges it into darkness (v. 23); "the eyes of the LORD are upon the righteous, and his ears are open unto their cry" (Psalm 34:15); "the eyes of the LORD run to and fro throughout the whole earth" (2 Chronicles 16:9); "his eyes were as a flame of fire" at His return (Revelation 1:14; 2:18; 19:12). The Christian disciplines the eye because what enters there fills the soul. Job made a covenant with his eyes (Job 31:1). Make the same one.
EYE, n.
1. The organ of vision or sight, properly the globe or ball moveable in the orbit. 2. The figure of the eye is the symbol of vigilance, foresight, observation, and intelligence. 3. The single eye — in Matt. 6, an emblem of singleness of heart toward God.
Matthew 6:22 — "The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light."
Psalm 34:15 — "The eyes of the Lord are upon the righteous, and his ears are open unto their cry."
Hebrews 12:2 — "Looking unto Jesus the author and finisher of our faith."
Revelation 1:14 — "His eyes were as a flame of fire."
Modern eye-culture is double-tongued screens; the single eye is in short supply.
Christ's saying in Matthew 6:22-23 is one of the most quietly devastating in the Sermon on the Mount: the light of the body is the eye. What you set your eye on becomes the lighting of your whole life. A single eye — one direction, one Lord, one allegiance — floods the body with light. A divided eye — chasing two masters, two kingdoms, two loves — plunges the whole body into darkness.
Modern Christianity often is gymnastically double-eyed. We follow the Lord and the algorithm; the Word and the influencers; the kingdom and the brand. Christ allows neither divided allegiance nor distracted vision. Cut what divides the eye. Fast from the screen until your single eye returns. Look unto Jesus — that is what Hebrews 12 commands. The runner sets his eye on the finish line; the saint sets his on the Lord.
Hebrew ayin (H5869); Greek ophthalmos (G3788).
"What you set your eye on becomes the lighting of your whole life."
"A divided eye plunges the whole body into darkness; cut what divides it."
"Fast from the screen until the single eye returns; the Lord is worth seeing."
