In the beginning was the Word, and the Word was with God, and the Word was God. – John 1:1
Light does something unique, it eradicates darkness. It is not a gradual thing but an immediate desolation. When you walk in to a room and turn a light switch on the room brightens and everywhere the light reaches darkness cannot overcome. No matter how much it may want to it simply cannot exist at the same time. Light provides assurance that darkness cannot overcome it because it is a fact we can see and observe.
So why is it we let the enemy win and cause doubt when God is the light? The very first words God spoke during creation were “Let there be light…” and then immediately darkness was separated from the work God was doing. His word commands the universe and move things just by that alone. We can see the light He created, the darkness of night, the air and land and sea He spoke in to existence. We have all these awesome tangible proofs that God exists and that God’s word can literally move mountains. Still we question his omnipotence. God is not as simple as a light switch but we get more assurance from a light switch than God and there is something wrong with that.
The first five verses of John 1:1-5 are the introduction of Jesus to the world. God not only gave us the Bible, His word and history put to paper but His Son as well. Jesus was with God from the beginning and through God all things have been made. Jesus is life for the dead souls buried in sin, the light in Him is given to us when we recognize and submit to God’s will for us. Believing in the divinity of Jesus and that His suffering has absolved us of sin on our judgement day is the assurance that God has given us freely.
Christ is Assurance
Sin is equated with darkness because that is where the serpent hides. Salvation through Christ is equated with light because of what light does. It is the simplest way God can show us the change that happens when you are redeemed. Light removes darkness and as such it removes sin. Light can make the serpent slither away because it prefers dark warm places where it can continue it’s work against God. These visualizations help us better understand why Jesus lives in us. He is the light and our hearts are dark and full of sin. The assurance that light eradicates that darkness is why we should be placing more faith in God than a light switch. God is eternal, the switch will eventually wear out or the bulb will blow. Jesus isn’t going anywhere. He is here and always has been.
