HeartKnows - Modern Devotion to the Sacred Heart
was revealed to St. Margaret Mary Alacoque
"COME TO ME, ALL OF YOU WHO LABOR AND ARE HEAVILY BURDENED, AND I WILL GIVE YOU REST. TAKE MY YOKE UPON YOU, AND LEARN FROM ME, FOR I AM GENTLE AND LOWLY IN HEART; AND YOU WILL FIND REST FOR YOUR SOULS. FOR MY YOKE IS EASY, AND MY BURDEN IS LIGHT."
In the past, the Devotion to the Sacred Heart of Jesus, that has a long history in the Church, had developed among people above all out of so-called "revelations" of a private sort, such as those to Saint Marguerite Marie in the 17th century.
The Devotion to the Sacred Heart also reminds us that Jesus gave Himself "with all His Heart," that is: gladly and with enthusiasm. So we are told that good is to be done with joy, because there is more joy in giving than in receiving (Acts 20:35) and "God loves a cheerful giver" (2 Cor. 9:7).
