St. Paul addresses the people of Ephesus: You “were sealed with the promised Holy Spirit, which is the first installment of our inheritance.” He is telling those early Christians, and us, that we have a foretaste of the glory to come with the presence of the Holy Spirit in our hearts. The Holy Spirit is the first installment, the down payment, that provides blessed assurance of our destiny with God. One of the infallible signs of the Spirit is joy. Pope Francis called his first encyclical The Joy of the Gospel to emphasize the importance of the presence of joy in spreading the good news of Jesus. No more sour Christians, he advises. Let us show forth we have the Spirit by sharing joy today.
