This reminds me of a story, if you don't mind me sharing.
I went on a men's retreat about a month ago. The retreat dealt with grief. One man, while we were sitting around the campfire on Saturday night gave a testimony of why he was there at the retreat(he is not a member of the parish that put on the retreat, neither am I, I went with my future father and brother in-laws). I hope I can remember it clearly. It went something like this.
He was baptized Catholic but non-practicing and an avowed atheist. His wife was a non-practicing non-denominational christian. Well his wife 6 years ago found out that she was diagnosed with cancer, she was given 6-12 months to live, and was told that she would not be able to have a baby(ovarian cancer?). Faced with this dilemna and suffering, she decided to seek God, so she started going to church, and because she wanted her husband to come with her, she went to the Catholic Church (St. Anne's, BrotherKnight) and dragged him along. She became on fire for Christ, entered RCIA (dragging her husband along with her) and became Catholic. She then started volunteering for the Church, teaching RCIA, being very active.
Well about 4 1/2 years later, not only was she still alive, but she also found out she was pregnant. The doctor telling her that she would not be able to survive the pregnancy, told her that she would need to get an abortion. She absolutely refused to do so. Well 6 months ago she gave birth to a baby, and the next day died.
The husband is now a single father of 3 children. During his telling of the story, it absolutely amazed me the serenity, faith, and love this man had. It was one of the most beautiful experiences I have ever had to hear a man, a former atheist, give testimony to the power of faith and love, absolutely astounded me.
