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!
