If it doesn’t happen, what happens to that person’s soul after they die?
Consider the life of St. Augustine. This famous son of St. Monica was born in Africa and spent many years of his life in wicked living and in false beliefs. Though he was one of the most intelligent men who ever lived and though he had been brought up a Christian, his sins of impurity and his pride darkened his mind so much, that he could not see or understand the Divine Truth anymore.
Notice, he says .... "our heart is restless until it rests in you." God calls to all men; it tugs at their hearts (ref. St. Bakhita). One can either respond or ignore it. In contemporary society, as God is gradually removed from society, the void is filled with self justification and gratification. No amount of money can bring joy or peace to the heart. The gnawing of God's call increases and a conflict is set in motion. I hear so many stories of youth who, despite a good education and plenty of electronic 'toys', remain restless. Some take their own lives.
St. Augustine's mother is St. Monica. She prayed for him daily. When he had become a Manichaean at Carthage, she appealed for support from her bishop. He consoled her with the now famous words, "the child of those tears shall never perish."
Each day, people find themselves in circumstances that test their ability to cope. You and I know the answer is to turn to God. In your concern for lost souls, like St. Monica, you should consider devoting a portion of your daily prayers for them. You may have recently read about a young woman who shot a video of her abortion. In an interview a few days later, she confessed that if her home were on fire, she would grab the sonogram image of the child she aborted. One blogger posted photographs of this woman before and after the abortion. The transformation was dramatic. In the before image, she looked alive and radiant with internal joy. In the after photo, her face is forlorn, her expression dour and depressed. We may never know what truly prompted her to go through with this heinous act but now, she, like so many others, is a victim. I pray for all of these victims each day.
What happens to these souls is between them and God. Pray for them!
