God says to Pharaoh, “I am the light of the world. It’s terrible when I’m excluded.” In the darkness there is disorientation. There is no plague more terrible than total darkness in hearts.

God asked Moses to release the darkness so that the Egyptians might know their condition. It got dark for three days. This is the absolute disorientation. But in Exodus 10:23 we read, “The people of Israel had light where they lived”.

God wants to redeem people and show them the way out of darkness. Everyone chooses for himself whether he wants to remain in Egypt or join the people of God.

The plagues are about the revelation of the power of God against the power of the gods of Egypt. The first plague affected the Nile, one of the most important gods of the Egyptians. This is about the main god: the sun. Re or Ra is the ancient Egyptian sun god. This means that the sun itself is a god and therefore was not created by a divine being. From this sun god the pharaoh borrowed his power, authority, and name.

David writes in Psalm 27:1: “The Lord is my light and my salvation”.

In Isaiah 49:6 it says about the Messiah: “I will make you as a light for the nations, that my salvation may reach to the end of the earth.”

John writes in John 3:19, “This is the judgment: the light has come into the world, and people loved the darkness rather than the light.”
