1 John 1:5 - "...God is Light, and in Him there is no darkness at all."
Genesis 1:4 - "God saw that the light was good; and God separated the light from the darkness."
Job 33:28 - "He has redeemed my soul from going to the pit, and my life shall see the light"
Psalm 18:28 - "For You light my lamp; The Lord my God illumines my darkness."

Ephesians 5:8 - "for you were formerly darkness, but now you are Light in the Lord; walk as children of Light"
God is Light, and through Him our darkness is illumined and we are light too. God isn't just bright or kind of light or more light than us, He is Light. There is no darkness in Him at all. We were darkness, not dark or a little dim or dark just in comparison, we were darkness. But He lights our lamps. He shines in our darkness. He makes us His children of Light. His children. We haven't just been altered, we have been made entirely new. We were once the opposite of light, darkness, and now we are the opposite of darkness, light. We were nothing like light. We were full of sin and error and darkness. And now we are full of light and goodness and Him.
When Job was afflicted, he looked to the light. He saw that God was light and that one day he would see that light, even if it was after a world of darkness. The psalmist too saw that God was light, and had the power to light. And not just to light anything, but to give light to the darkness that is us. Solomon tells us about the light of the righteous rejoicing and the light of the wicked going out. Thanks to God's grace we share His righteousness and therefore His light too. And Paul encourages us to walk as children of Light, children of God.
Unfortunately, sin blocks His light from shining through us. Pride blocks His light with our own conceited darkness. Lust blocks His light with our own dark desires. Gossip blocks His light with the harm of others. Hate blocks His light with our human hearts. Sin blocks God's light with our darkness. But by grace we are free from sin, we are conquerors of sin, we are children of Light! So through song, through service, through gathering, through speech, through teaching, through encouraging, through giving, through whatever means available let Him shine through us. Pray that His light would be ever stronger through our vessels and that our darkness would continually grow weaker and dissolve more.
