155 We may also question how we can pray to the Lord of life, risen from the dead and reigning in glory, while at the same time comforting him in the midst of his sufferings. Here we need to realize that his risen heart preserves its wound as a constant memory, and that the working of grace makes possible an experience that is not restricted to a single moment of the past. In pondering this, we find ourselves invited to take a mystical path that transcends our mental limitations yet remains firmly grounded in the word of God. Pope Pius XI makes this clear: “How can these acts of reparation offer solace now, when Christ is already reigning in the beatitude of heaven? To this question, we may answer in the words of Saint Augustine, which are very apposite here – ‘Give me the one who loves, and he will understand what I say’. Anyone possessed of great love for God, and who looks back to the past, can dwell in meditation on Christ, and see him labouring for man, sorrowing, suffering the greatest hardships, ‘for us men and for our salvation’, well-nigh worn out with sadness, with anguish, nay ‘bruised for our sins’ ( Is 53:5), and bringing us healing by those very bruises. The more the faithful ponder all these things the more clearly they see that the sins of mankind, whenever they were committed, were the reason why Christ was delivered up to death”.
