A reminder about what you are.
Sometimes a reminder of who we are really helps us get back on our feet. Hebrews 9:23 says, "Therefore it was necessary for the copies of the things in the heavens to be cleansed with these, but the heavenly things themselves with better sacrifices than these."
As Christians, we are the heavenly things. As Heb 12 would say, "you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to myriads of angels." In Christ, we have received the best sacrifice and the best blessing. In Christ, we can accomplish far more than we ever thought possible. There's no reason to hold back from utter excellence, and to show up to others as something different than what the world has to offer—a truly heavenly thing.
