From the Thoughts and Prayers of Mother Teresa
If you are joyful, it will shine in your eyes and in your look, in your conversation and in your contentment. You will not be able to hide it because joy overflows.
Joy is very contagious. Try, therefore, to be always overflowing with joy wherever you go.
Joy, according to St. Bonaventure, has been given to man so that he can rejoice in God because of the hope of the eternal good and all the benefits he receives from God. Thus he will know how to rejoice at his neighbor's prosperity, how to feel discontent concerning empty things.
Joy must be one of the pivots of our life. It is the token of a generous personality. Sometimes it also a mantle that clothes a life of sacrifice and self-giving. A person who has this gift often reaches to high summits. He or she is like a sun in a community.
We should ask ourselves, "Have I really experienced that joy of loving?" True love is love that causes us pain, that hurts, and yet brings us joy. That is why we must pray and ask for the courage to love.
