There are three major movements in scripture that highlight the power meaning of light. One, the creation of the world (Gen 1:1-3). Two, Christ’s incarnation (John 1:1-5). And three, the new Heavens a new Earth being formed (Rev 22:1-5).
Each of these movements were acts of creation to bring about something new. Movement one, the world is made. Movement two, the Word became flesh, which in itself is an act of creation, but also, what Jesus came to do was to create a whole new thing in the Church. The body of Christ is a creation. Those who put their faith in Jesus are called a new creation in 2 Corinthians 5:17. That new creation is not supposed to behave, think, or even feel like the old self, but like the new self. (Ephesians 4:24, Colossians 3:12-14, Romans 6:6) At the end of time God is going to remake all things into a new heaven and a new earth. This act of creation is talked about in Isaiah 65:17, Hebrews 12:26-27, and Revelation 21:1).
Each of these movements had the same centerpiece, which is Jesus. How did God create everything? He spoke it into existence. Colossians 1:15-17 states it was by Jesus, through Jesus, and for Jesus that all things were created. How can this be that Jesus created all things when Genesis 1 doesn’t mention Jesus? Well it does actually. Pair Genesis 1 with John 1. The very words God spoke were Jesus. He is the word, which is also why Jesus can say that all scripture (God’s word) is about Him in John 5:39. In the final creation it will be the Lamb and the Almighty who serve as both the light and the temple. From beginning, middle, to end, we see Jesus at the center of it all.
Each of these movements had the same purpose which is to bring life. Often light and life are interwoven. We need light, plants need light, animals need light. According to healthline, light gives us well needed vitamin D, helps with mental health and focus, and improves our circadian rhythms and sleep patterns. Light is life-giving.
In John 1 Jesus is both the light and the life of men. In Colossians 3:4 Jesus is also referred to as our life. In John 8:12 Jesus is proclaimed as the light of the world. Those who follow Jesus are also called the light of the world. Just as Jesus brings life, we are supposed to be little life-givers ourselves. Our words and actions should inspire and encourage and strengthen the weak and downhearted. We should be serving, loving, sharing, and speaking truth and life to those around us. Where Jesus goes, life goes, therefore where followers of Jesus go, there life should be also. God created life in the beginning, but first had to make light. God created a new life in Jesus, but first the eternal light had to become flesh and enter the world. God will create a new glorious life in the age to come, but first He will become the light and life that shines through it all.
