The old ways that the Colossian believers used to live had to stop. Their old ways of thinking, speaking and acting were sinful. These ways caused harm to them and their communities.
The Colossians had to stop obeying their sinful desires because they now had new life. Jesus is the centre of the new life of all believers. Paul said that Jesus is everything and is in everything. He meant that Jesus is the most important one who exists. Nothing is beyond Christ’s rule.
Because of this, the ways that human beings divide into different groups no longer matter. God’s people are to live together as one body. This is possible because the peace of Jesus rules in their hearts. When they understand how dearly God loves them, they can love one another.
