I was in the WCG too. Being exposed to the law showed me my inability to keep it, this is how the law led me to Christ. I stopped working, trying to keep a law that I never could. I took a Sabbath in Christ and now God works in me and now every day is holy rather than one day of the week. It seems that the bad experience of the WCG was turned to good. All things did work for good. It matters not what we came out of, we all need to put that behind us and move forward in our calling. Let them alone and they will fall into the ditch. Focus on Christ don't look back once your hand is upon the plough.
