Creation began when God said, “Let there be light.”
Redemption begins with the same declaration, “In him was life, and the life was the light of all people” (John 1:4).
Like natural life, born out of the darkness of creation (Genesis 1:2) and of the womb, the spiritual life comes out of the darkness of sin into the light of salvation (e.g. Isaiah 9:2, Matthew 4:16).
This actually means that we live, move, and have our being in God, for God is Light (1John 1:5). When we walk in darkness, we walk at cross purposes with our very existence; when we walk in the Light, we walk in sync with it.
Nicodemus came to Jesus “by night” (John 3:2), both literally and figuratively. Jesus’ transforming conversation with him, tending toward new birth, was a conversation about moving from darkness to light (John 3:19-21).
God’s conversation with each of us about the same movement. We are made for the Light!

Spent an afternoon in a theater-like worship center yesterday for a District Conference. Woodlake United Methodist Church. Found it very unpleasant without windows to the outside light. I feel very closed in when I visit Assembly of God Churches that have no windows…..so am wondering about the tabernacles of the old testament….Thanks for this writing about the Light of the World. Today where I am located is a beautiful sunshiny day with a gorgeous blue sky outside my back window over the forest. Thanks be to God for His Natural Light….and for the Light of Christ which dwells in our hearts when we permit it.
