Light is something we almost take for granted. It is around us every day, and by it we see everything. It is also vital for life. Without light there would be no heat, and earth would be a frozen wasteland. It is light that gives the energy for plants to grow, providing food for other living things. Light is the first particular thing God is said to have created (Genesis 1:3; Psalms 74:16; Isaiah 45:7). But in Scripture there is a spiritual understanding of light beyond the physical (1 Corinthians 4:6). It is used as a symbol of God’s presence (Exodus 13:21,22; 25:31-40; Acts 9:3). This symbolism was shown at the Feast of Tabernacles, where Jesus proclaimed Himself the Light of the World (John 8:12), thereby affirming that He was the ultimate source of spiritual light (Isaiah 9:2; John 1:4,5; Luke 1:78,79). This statement was probably a response to the question whether any prophet could come out of Galilee (John 7:52; compare Matthew 4:14-16). In what ways is Jesus light?
