This is the beginning of what we call the “prison letters” of Paul. He was writing to people and congregations he had visited on his missionary journeys. This letter was written to counteract false teaching about how we are saved. He does this by pointing to the sufficiency and supremacy of Christ. It’s all about God’s image. What it is, what it means, what’s been lost, what will come. All connected to Christ. Our summary verse is from Colossians 1:15-16: ““He is the image of the invisible God, the firstborn of all creation. 16 For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things were created through him and for him.” – (ESV)
