in his name

“And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him” (Colossians 3:17).
 
Having just completed a discussion of the public worship of the church, the Apostle Paul broadens his scope in giving this instruction: he says not only in worship but in all aspects of living the Christian life, the Colossians should be mindful of the name or the authority of Jesus.
 
It is because of His power and His authority that spiritual activities here have any meaning to the Father in heaven—that is, it is because of Jesus that our adherence to God’s word counts toward our eternal inheritance. And we should be filled with thankfulness for this wonderful spiritual benefit.
 
Paul was leading the Colossians against false teachers who wanted to equate other beings with Jesus. Even though we may not be in the same position as the Colossians in this regard, we benefit greatly from this admonition. Every word and every deed should be guided by the authority of Jesus.
