MacArthur on Scriptural use of “light’

John MacArthur, “... light in Scripture is often a metaphor for holiness (Matt. 5:14–16; Rom. 13:12), for truth (Pss. 36:9; 119:105, 130; Prov. 6:23; Acts 26:23; Eph. 5:9; 1 Thess. 5:5), and also for spiritual life in Christ (John 1:4)...” [MacArthur, J. (2011). Luke 6–10 (p. 199). Chicago, IL: Moody Publishers]
