No problem.... God is literal light, it is not symbolic. Whenever God shows up, normally light comes as well (see ), because God is light. It is not that God is showing up and then flicking on a torch that He carries in His hand. Light is a fundamental attribute of His person, so wherever God is, light is there too, and no amount of darkness can overcome it. And this light brings truth. In Paul's conversion, in ; He saw the light, he heard the voice.. immediately He knew that Christ was real and was the Lord. No one had to teach Paul anything, and neither did Paul have to say "wait a minute Jesus, I have seen your light and heard your voice, give me a few minutes while I look up this experience in my study Bible, and find the actual verse which says that Jesus is real"). God shone His light on Paul, and immediately Paul knew the truth.
says that in the future there will be no need for natural light (sun) or artificial light, because God Himself will be the light.
We cannot always see this light, because it is spiritual and invisible, but it can become visible to us in the physical realm. Everything that God is, is real and can be experienced by us by praying to Him through Christ, whether it's love, or life, or light, or truth, or wisdom. If you seek God with all your heart and find Him (), you will touch Him and He will touch you and you will get love, life, light, truth.. everything. It is this experience that led the psalmist (probably David) to say
My soul yearns, even faints, for the courts of the LORD; my heart and my flesh cry out for the living God.
Psalm 84:10 10 Better is one day in your courts
than a thousand elsewhere;
I would rather be a doorkeeper in the house of my God
than dwell in the tents of the wicked.
Whom have I in heaven but you? And earth has nothing I desire besides you.
Why did God captivate David so much? Because David found that God was living (), God was his life, and from this, everything else, love, light, grace, truth, flowed.
It is fine to discuss these things, but at some stage, you will have to pray and seek God and experience these things for yourself. Then you will no longer have to ask "what is light?", because you will already have it and know.
What started as a simple question about love, has developed into realizing that God is so much more than just love, and so we can only praise Him for being such a wonderful and living God. Furthermore, we can know that this great and wonderful living God, limited and humbled Himself by becoming a man just like us, Jesus Christ, to die for our sins on the cross, and now, through Christ, God is approachable and relatable to us. If God is the light that is unapproachable and if we look at Him it will blind us or even kill us (, ), then Jesus Christ is like the light bulb (symbolically) who makes God approachable, viewable, and safe.
