I agree with previous posters that you should definitely not bring any pressure whatsoever on this girl to attend church. If she genuinely wants to go,that's fine, but it would be completely unacceptable for a Buddhist visitor in that situation to be made to feel that she "had to" attend a Christian church. Quite apart from anything else, it would demonstrate extreme arrogance on your part! As Richard says, Thais are very tolerant of other religions but that does not necessarily mean they are receptive to adopting Christianity and if that is your motivation I suggest you seriously consider not proceeding.
