“And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.” —Genesis 1:3-5
John the beloved disciple writes in his first general epistle “that God is light, and in him is no darkness at all” (1 John 1:5). God is certainly light, meaning that He is all that is holy; all that is bright; all that is illuminating; all that is of the utmost clarity; all that is the pinnacle of wisdom without a breath of folly; all that is the extent of power without a shred of weakness; all that is the supremacy of equity without a shadow of evil; all that is the excellence of goodness without any hesitation or withholding; and all that is the fullness of truth and knowledge without any mixture of error whatsoever. All that we know that is called “light” are those things that can give us a glimpse, and only a glimpse, of the holiness that God has revealed to us of Himself and about Himself.
In the first event of creation, God commanded, “Light be;” and light was. Illumination in creation broke forth in God’s spoken word, and a reflection of Himself filled the very first day of the creation of the universe.
God spoke. Why? God spoke because His was a prophetic utterance. Though the mere manifestation of His presence would in itself bring overwhelming light, God spoke of light in day one for there was that Day coming when the full glory of light would be revealed to the entire created universe. Jesus Christ is Alpha, and therefore, on day one God said, “Light be.” Jesus Christ is Omega, and therefore, in that Day the fullness of God’s glory will be manifested in, and through, and by the Son of God, “who being the brightness of [God’s] glory, and the express image of his person, and upholding all things by the word of his power” (Hebrews 1:3), His light will illuminate the fulfillment of all things by the fullness of His glory. It is written in John 8:12,
Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
God spoke because Jesus Christ, as the Word of God from the beginning, is the light of men that shines in the darkness, as it is written in the prologue of John’s gospel,
John Chapter One
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
5 And the light shineth in darkness; and the darkness comprehended it not….
9 That was the true Light, which lighteth every man that cometh into the world.
10 He was in the world, and the world was made by him, and the world knew him not.
God spoke, for Jesus Christ would one day come, and He would call His people “out of darkness into his marvellous light” (1 Peter 2:9).
