God is light and being a perfect God is Holy, He is the opposite of darkness; therefore, God would be light Himself. It’s plain to see all throughout the scriptures all good things comes from the Father of lights. See last post Jesus Christ is God John 17:3, 1 John 5:20
James 1:17 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
In the beginning of our Bibles, God (Elohim) spoke these words “let there be light” and there was (Genesis 1:3). At that moment darkness was divided from the light (Genesis 1:4) and we know that the LORD never has any part or affiliation with darkness.
When the Lord delivered the children of Israel from the bondage of Egypt, Israel was given light from the LORD, as He lead them through the wilderness (Exodus 13:21). God protected them from the Egyptian army which sought to destroy them. God kept the Egyptians separated from Israel as Moses would part the Red Sea (Exodus 14:20-23).
The Psalmist king David
As king David who was a man after God’s own heart spake by the Holy Ghost (Acts 1:16) could write about who the LORD is saying “The LORD [is] my light” again we’re confronted with this great truth that God is light. Through the light, our God leads us (Psalm 43:3) and directs our feet placing them on the right path (Psalm 119:105), He has shown us light (Psalm 118:27).
Psalm 27:1 The LORD [is] my light and my salvation; whom shall I fear? the LORD [is] the strength of my life; of whom shall I be afraid?
The Book of Proverbs
David’s son king Solomon also directed and guided by the Holy Spirit the wisest of all men told us in Proverbs that God’s holy Law is also light because it comes from God (Proverbs 6:23) anything which comes from God in its very nature would be light.
The prophet Isaiah cried unto the people of Israel as the LORD directed him saying “let us walk in the light of the LORD.” (Isaiah 2:5) Were also told that “a great light” which in reference to God would be shown to the people who walked in darkness (Isaiah 9:2). In Isaiah, we have a direct reference to the One who is called by God His servant and will come unto the Gentiles also know as the Messiah (Isaiah 42:6).
In the book of Daniel we have the account of the dreams which came to king Nebuchadnezzar of Babylon, the king making a decree that his dreams should be made known otherwise he would destroy all the wise men. Daniel hearing of this harsh decree sought the king asking for time to seek the LORD in prayer that He would make the interpretation known. Daniel was shown the interpretation by God and came to stand before king Nebuchadnezzar proclaiming these words about the LORD, “and the light dwelleth with him”.
Daniel 2:22 He revealeth the deep and secret things: he knoweth what [is] in the darkness, and the light dwelleth with him.
In the book of Micah, he gave thanks unto the LORD for being his light saying “the LORD [shall be] a light unto me” (Micah 7:8). Another prophet by the name of Habakkuk prayed to the LORD and it says that God came, the Holy One and “And his brightness was as the light” the text goes on to say “he had horns coming out of his hand” or rays flashing from His hand which speaks of His glory.
The New Testament
We’ve seen just but a few verses which speak of God Himself as being referred to as “light”, as we continue past the last book of the Old Testament. The first reference of God as light is found in the Gospel according to Matthew which says:
Matthew 4:16 The people which sat in darkness saw great light; and to them which sat in the region and shadow of death light is sprung up.
This verse in Matthew is pointing us back to the verse found in the old testament, the prophet Isaiah prophesied about a great light which would be shown unto the people who are in darkness. This is a direct statement concerning the coming Messiah and this was fulfilled by the Lord Jesus (Luke 1:79). Luke puts it this way that He (Jesus) was “A light to lighten the Gentiles, and the glory of thy people Israel.” (Luke 2:32)
Immediately following that verse we have the Lord Jesus preaching to the people saying “From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.” (Matthew 4:17). This brings us to another important event called the mount of transfiguration, the Lord chose Peter, James and John to accompany Him to the top of the mountain as the rest stood behind at the base (Mark 9:1-2, Luke 9:28-29).
When the Lord Jesus prayed the scriptures say He was transfigured and His countenance became “raiment became shining, exceeding white as snow; so as no fuller on earth can white them” (Mark 9:3) or “his raiment was white and glistering” (Luke 9:29).
In the Gospel of John, the apostle says that in Jesus was life and that life was the “light” of men (John 1:4). Jesus Christ is the origin or source of light itself. John then compares Christ to the surrounding darkness of this world.
John 1:4-5 In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.
John the Baptist was the forerunner spoken of in the book of Isaiah who would proclaim to Israel the coming of the Messiah (Isaiah 40:3), John references this and mentions that John was a witness to “the Light”.
John 1:7-9 The same came for a witness, to bear witness of the Light, that all [men] through him might believe. He was not that Light, but [was sent] to bear witness of that Light. [That] was the true Light, which lighteth every man that cometh into the world.
When Saul (Paul the apostle) was persecuting the church he was on the road to Damascus and was visited by the risen Lord, Luke the physician tells us that Saul saw “shined round about him a light from heaven” (Acts 9:3). Paul after his conversion gives his testimony of coming face to face with Christ Jesus and said to the chief captain and Hebrew people in the Hebrew tongue.
Acts 22:6, 9, 11 And it came to pass, that, as I made my journey, and was come nigh unto Damascus about noon, suddenly there shone from heaven a great light round about me. … And they that were with me saw indeed the light, and were afraid; but they heard not the voice of him that spake to me. … And when I could not see for the glory of that light, being led by the hand of them that were with me, I came into Damascus.
Paul gives his testimony again before king Agrippa saying how he saw a light from heaven on the road to Damascus. And that Christ was a light shown unto the people and Gentiles (Acts 26:23).
Acts 26:13 At midday, O king, I saw in the way a light from heaven, above the brightness of the sun, shining round about me and them which journeyed with me.
In the epistle to the Corinthians Paul tells us that the light of the Gospel is which speaks of Christ Himself, the Lord Jesus is that light but satan is keeping people blinded to that light (2 Corinthians 4:4).
2 Corinthians 4:6 For God, who commanded the light to shine out of darkness, hath shined in our hearts, to [give] the light of the knowledge of the glory of God in the face of Jesus Christ.
In the epistle to the Ephesians, we’re told to awake and Jesus Christ will give us “light” (Ephesians 5:14). The book of 1 Timothy tells us that God the Father dwells in “light which no man can approach unto” (1 Timothy 6:16). The apostle Peter tells us that believers are called out of darkness “into his marvellous light” (1 Peter 2:9).
John the apostle in his first epistle tells is this fact which is “God is light, and in him is no darkness at all”. How pure is the God that we serve, complete Holiness and purity.?!
1 John 1:5 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.
John goes on to say how believers are to walk in the light as the Lord Jesus is in the “light” that we may have fellowship with our Lord (1 John 1:7). He calls Jesus “the true light” (1 John 2:8).
The last book of the Bible, Revelation speaks of the Lamb of God who is the “light and glory of God” (Revelation 21:23), and that God is the one who gives this light.
Revelation 22:5 And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
We hope that this was edifying to you and helps you in your studies in seeing that the Lord Jesus is God.
John 9:5 As long as I am in the world, I am the light of the world.
