Prayers sent.
Now here is something that may help, and the fact that “abortion” was just in my thoughts, hopefully God sent me to tell you to do this. I used to have a problem with some sins regularly for many years. It wasnt until recently when before I went to confession, I really focused on every sin, and how it offended God. I needed for once to forget what the world puts in our heads as normal, and focus on the disgust. Even if we didnt do things we thought were wrong. Or we didnt do them for that intention. I now get disgusted when I think of sins that I was doing on the regular. I was just examining myself, to see if I havce been improving in my faith, and I was seeing that im now disgusted my abortion. Before I just knew it was wrong, dont do it. But now im truly disgusted by it. Thats what I was thinking about before I came across your request. So I would tell your peers to make a confession, and truly focus on what they did, and how it offended God. Even if it takes 5-10 minutes for each sin. No matter how long it takes, truly focus on how everything they did in the past offended God. Hopefully they will feel disgusted about abortion like I do now.
