Rejoicing in the Lord means knowing Jesus Christ as our Lord, Savior, and Treasure. It means he gives us deeper, purer, sweeter, more lasting pleasure and gladness than anything this world has to offer. As Paul says in Philippians 3:8, “I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord.” Rejoicing in the Lord means that there is a new song in our hearts — the song of the redeemed — that the din and distresses of life cannot drown out. He is the chief object of our joy.
