In a recent Gallup poll it was revealed that in every statistical category there was a demonstrable decline in excellent mental health... with one exception. In fact, this one demographic of people even saw an increase in excellent mental health in the year 2020. Can you guess which demographic that was?
People who worship weekly.
At the conclusion to Paul's first letter to the Thessalonians he reminds them of that God wants them to be joyful, thankful, and faithful, and that the way God gets them there is by giving them his Spirit through the preaching of his Word.
If you want to be joyful, thankful, and faithful, try the same thing. Be diligent in devotion, willing to worship, and discerning in what you digest in this world.
Fill yourself with God's Word and know a joy that cannot be crushed by any circumstance in life - not even if Christmas gets cancelled.
