111 This being so, there is no doubt that Christians in paying homage to the Sacred Heart of the Redeemer are fulfilling a serious part of their obligations in their service of God and, at the same time, they are surrendering themselves to their Creator and Redeemer with regard to both the affections of the heart and the external activities of their life; in this way, they are obeying that divine commandment: "Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with thy whole mind, and with thy whole Strength."(113)
