Rejoice always. (1 Thessalonians 5:16)

When St. Paul tells us to “rejoice always” (1 Thessalonians 5:16), it might seem that he is asking the impossible. How can we always feel joyful? Isn’t this too much to ask, even today, on Gaudete (or “Rejoice”) Sunday?

Not according to St. Thomas Aquinas! He taught that “joy is caused by love” (Summa Theologiae II-II, q. 28). As we experience God’s love for us, we grow in love for him—and this exchange of love is what produces joy in us. St. Paul also knew that God’s love was the secret to joy, which is why he follows up his exhortation to “rejoice always” with specific steps that we can take to experience his love more deeply:

First, pray without ceasing (1 Thessalonians 5:17). When we open our heart to God throughout the day, he fills it with his very self. The experience of his unconditional love and unending mercy ignites our love in return.

Second, in all circumstances give thanks (1 Thessalonians 5:18). Gratitude also deepens our love for God, especially when we reflect on who he is and what he has done for us. And in this Advent season, whatever our circumstances, we can thank God for sending his Son to earth to become one of us.

Finally, do not quench the Spirit (1 Thessalonians 5:19). In his Letter to the Romans, St. Paul tells us that “the love of God has been poured out into our hearts through the Holy Spirit” (5:5). If we want more joy in our lives, we can ask the Spirit to stir up the love of God in our hearts. And when he does, we can express it by praising him—which will, in turn, increase our joy.

Joy is not just for Gaudete Sunday; it’s for every day. So each day, follow Paul’s advice: turn to the Lord in prayer, thank him for all he has done for you, and ask him to fill you with more of his Spirit. Then praise him—and let your spirit soar!

“Lord, shower me with your love today so that my heart swells with joy!”
