In the natural world, we are illuminated by the sun’s light. Since we have eyes in our physical bodies, we need light to see where we are and where we need to go. Additionally, we require it to recognize and avoid the numerous threats that surround us. Because the dark conceals those threats, we naturally have a natural fear of it. Haziness cloaks animals, lifeless things, and conditions that can truly harm or kill us. We have no idea what to do in the dark, either.

However, the sun also literally gives life to our bodies. We must either consume plants that consume light or animals that consume plants that consume light in order to survive. In addition to directly absorbing essential nutrients from sunlight, our bodies would not be able to survive without the heating effect of this electromagnetic radiation.

As a result, natural light literally gives and sustains our physical lives, teaches us how to proceed, and reveals the truth about our surroundings.

The same is true of the divine spiritual light that David speaks of in Psalm 36:9, the light that God is (1 John 1:5), and the light that God gives (Revelation 21:23–25), all of which are frequently mentioned in the Bible:

We are shown the way by divine light. According to Psalm 119:105, “Your word is a lamp to my feet and a light to my path.”
What is true about our spiritual surroundings is revealed by divine light. “For those who dwell in the region and shadow of death, a light has dawned on them, and the people who dwell in darkness have seen a great light” (Matthew 4:16).

Spiritual life is literally provided by divine light: According to 2 Corinthians 4:6, “God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in Jesus Christ.”
In Psalm 36:9, David used the words “life” and “light” interchangeably. Because, like natural light and life, spiritual light and life are intertwined.

However, there is extremely encouraging news for everyone residing in such darkness. According to John 1:9, Jesus claimed that “the true light, which gives light to everyone, [came] into the world] precisely to dispel this great darkness.” He adds, “I am the world’s light.” The light of life will shine upon those who follow me, not in darkness. John 8:12) Carefully reread that.

Read this now: According to John 1:4, “He was life, and the life was the light of men.” What see you? When you look at Jesus, you are looking at the incarnation described in Psalm 36:9: We can see light in your light.
