There is no doubt about it. By uniting ourselves with Christ, in prayer, and in patient acceptance of our sufferings and humiliations, for love of Him, and by our intercessions for people in need, we are saving many from committing mortal sin, or from dying unrepentant and falling into Hell.
People who suffer persecution or martyrdom because of their faith in Christ can feel as though they are leaving a garden of earthly delights to enter an endless tunnel of suffering. They can be assured that that tunnel opens out onto an area: not an area like the Colisseum, but a place where Christ, His Mother and all the Saints wait to greet them, and lead them into a life of Eternal bliss.
Christ is never indifferent to our pains and sufferings. No-matter how alone we feel, we should believe that He is close by at work to ease our sufferings and to bring us help in the midst of trails. It is as if He has His arms round each individual, holding each one close to His heart.
Every detail of our lives is of interest to God, Who loves us as a good father loves his children. Whatever good things we do, God is willing and able to help us with them, whether we build, make music, nurse the sick, or paint for His glory and to delight or help other people. He cannot help us to do evil - though He can bring good out of the evil we do.
Someone who doubts the Real Presence of Christ in the Blessed Sacrament should ask himself: if a man can invent a means of downloading tremendous amounts of information and imagery onto hand-held computers and mobile phones, cannot God, Who is almighty, have used a means of 'downloading' Himself 'into' the small white disc (which is truly Christ Himself) which we call the 'Sacred Host', at Mass?
