By Colossians 3:17 And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.
The lordship of Jesus ought to be the central aim of the Christian life. When Kerry heads off to Ukraine, he represents the United States in all that he does and says. He functions as a representative or an ambassador. It is the same with the Christian. All that we do and all that we say reflects the lordship of Jesus in one way or another. It either represents Jesus in a way that brings him glory or brings him shame.
I work for a company that desires their workers to wear hard hats 100 percent of the time. This hardly is ever obeyed except when we (the workers) are in an environment where there are observable dangers overhead. Jesus desires that his workers wear their helmet of salvation all of the time. He does not want to leave it in the hands of his workers to decide whether there are overhead dangers or not. He simply wants them to trust that he knows best, and has a genuine care for their well-being.
