When praying FOR SOMEONE TO HEAL are you not asking God to change his plan for that person?
If you believe that God has a plan for everything, then who are you to try to get him to change it? Praying for THESE THINGS is both sinful and useless.
Please note: CAPS is used to emphasize certain words, please pay attention to them
ETA: Just to let you know, I've had some wonderful conversations with some great ladies about this. Although I am reading all of the replies I'm only going to answer if I really feel the need to because something you have said has not been said. Most of the newer replies are not getting the point of the question, which is why I'm not answering.
Thank most of you for keeping this a civil and interesting conversation - I appreciate all your insights!
