Prayer for the last day of the novena. O Saint Margaret Mary, who by a special predilection were chosen by God to propagate the devotion and worship of the Most Sacred Heart of his Most Holy Son! By the burning love which the Holy Spirit infused in you for the Divine Heart of Jesus, by the great contradictions and labors which you suffered in carrying out your enterprise, by the eminent merits and immortal crown with which you are happily adorned in glory, I beseech you to obtain for me from the Lord an ardent, tender and constant love for the Sacred Heart of Jesus, and that in imitation of you my heart may become like His; and that receiving His influences copiously, I may consecrate myself entirely to His love and service and live only for Him, and die in the bosom of His love, so that my soul may go on to glorify Him eternally in heaven in your company. Amen
