Lord I pray that you will lead Carol to know you. We do not have the power to save anyone. Some plant and some water but Jesus provides the growth. Lord help this guest to continue to pray and not worry what to say. You said you would give us what we are to say when the time comes. Let this guest be a shinning light by their example and if necessary use words. Indeed draw Carol's heart to you Lord that she may know the joy of salvation and the forgiveness of sins. In Jesus name I pray.
