This OW/OM topic is very interesting. When I was dealing with this and so very angry because of what I found out, the Lord took me to the Bible Story about the adultress that everyone wanted to stone because they caught her at it.
The Lord asked me if I remembered what his response was? I said yes and he asked me then who threw the first stone? I said no one and he said why. I said because none of them could say that they were without sin. He said I am finished.
I thought great I've just started. So yes, there are many emotions that go through a person when you find out things like this. It is very hard and very difficult process to get through. Do you know why the Lord asks you to pray for the OW/OM? Because you know what they are doing and you know what to pray for. You also pray for them because then the Lord can help to heal you and make you stronger.
It is a very difficult thing to deal with for the person who it is done to and for the people who are in the act of it. It just takes time to get through it and to get past the pain that you feel as it takes them the time to get past the guilt.
See sometimes we are so caught up in our own pain and hurt that we forget that they are now emotionally connected as you might call it. They are feeling things that are very hard to admit that they could have for someone else. I think that is a very hard thing to have to truly look at. I think that it is easier to believe that they were taken over and dragged into something and had no idea what they were really doing instead of thinking that they made the choice to do exactly what they did.
Everyone has to work through this in their own way, but also has to remember that the OW/OM is still a person that the Lord created that right now is not following the Lord, but following Satan.
