I just wanted to add two points to sandi's excellent post on faith.
I find it interesting that right after stating your uncertainty of the existence of God, your W agreed to attend a religious M retreat, and asked for it sooner than later. God works in mysterious ways :). Who is to say today isn't that day, and that this whole situation has been a pathway for you? Certainly you have heard the expression "Leap of Faith". Faith is a decision to believe without having physical proof, or a decision to not believe, but either way it is your decision and no one else can make it for you.
Also, the greatest illusion that Satan ever perpetrated was that he doesn't exist.
I honestly don't know how I could make it through this trying time in my life without faith - it really is the only thing keeping me going. [/soapbox]
