The scripture for today is Genesis 1:3
Genesis 1:3 And God said, let there be light: and there was light.
At the beginning of creation, God established a divine principle; light dispels darkness. And how does God bring light into the dark places? He does it through His Word. The phrase "God said" is repeated ten times in the first chapter of Genesis. "This phrase, which occurs so repeatedly in the account means: willed, decreed, appointed; and the determining will of God was followed in every instance by an immediate result." Jamieson-Fausset-Brown Commentary When God speaks, He has willed and appointed a thing and what He has willed and appointed is exactly what is going to happen. This principle is repeated over and over in the creation account.
The primary source of natural light is the sun. Light can also be produced by other means. Lightning, fire, electrical devices, etc., are all sources of light. The light that God spoke into existence was not only the natural illumination that provides us the ability to see how to do things physically. He also "willed, decreed and appointed" His very presence into all of creation. The source of true light is not the sun, but God. "This then is the message which we have heard of Him, and declare unto you, that God is light, and in Him is no darkness at all." 1 John 1:5 God who brings light out of darkness can shine into the darkness of hearts and bring those who accept His light unto Himself. "For God, who commanded the light to shine out of darkness, has shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ." 2 Corinthians 4:6
In a very real sense when God said "let there be light," He was bringing to bear the presence of His glory upon all things. That presence and glory has been expressly manifested to mankind through Jesus Christ. He is the Word of God; He is the light of God revealed to the world so that no one has to remain in darkness.
God bless you as you continue in His service.
