Is Your Light On?
May 24, 2026
Did you know that if the sun’s light ceased, the earth would freeze within days? All plant life would die, the oxygen would collapse, and humanity would perish within weeks, leaving our planet a frozen, silent slab of rock. That is how foundational light is to every form of life. One of the greatest statements Jesus ever made speaks to how essential He is to the cosmos, the culture, and our own souls: “I am the light of the world” (John 8:12, NIV). John picks up that truth in 1 John 1:5–10 and makes it deeply personal, asking us to do something harder than just flipping a switch for illumination. We are to honestly ask whether we are walking in the light or just saying that we are. There are four things John tells us we must keep doing if God’s light is truly living in us.
