Colossians 1:15-27 is one the great Christological passage in the NT. It lays out how Christ is supreme over all things, and has now reconciled all things to himself through his death on the cross. He is both the firstborn over all creation and the firstborn from among the dead. This means His death on the cross didn’t just save sinners and release forgiveness to them. His death defeated all the principalities and powers in the invisible realm and reconciled all of creation in the visible realm to Himself. We now get to partner with Him as the first fruits from among the dead, to see His Kingdom ushered into the here and now. Salvation is both a future and present event, so let’s start ruling and reigning on the earth with Him today.
