Our parish received a letter from Mother Teresa which [in part] said:
“Each one of us is a co-worker of Chirst - we must labour hard to carry Him to the hearts where He has not yet been known and loved. But, unless we have Jesus, we cannot give Him; that is why we need the Eucharist. Spend as much time as possible in front of the Blessed Sacrament and He will fill you with His strength and His power. Tell Him, ‘Come to our hearts Lord and stay with us.’ Then you will become the instruments of His love, peace and joy.” -Excerpt from Mother Teresa letter, July 15, 1996
