How do you say good-bye?

...to everyone and everything? We've said goodbye to family in August, more family at Thanksgiving, still more family in December...but starting to say goodbye to friends here is almost more difficult because it comes so close to actually leaving and along with all the work of packing and moving.
We have the greatest church (hooray for Peace Lutheran!) that we've belonged to for over 10 years. Yesterday they had a wonderful commissioning during the service and a great reception between services. We were amazed and so thankful for the outpouring of good wishes and prayers and humbled by the confidence that everyone seems to have in us! I just don't know how people get through times of change or stress (or life in general) without the support of a faith community and a belief and trust in God. At this point, it's becoming more evident how important that is. We are leaving in three weeks--the well drilling for water on the land is still in progress, we have not heard about housing for when we arrive, nor have we heard anything about our work/residence permits. Who else besides God can we trust to see us through whatever is coming?
To everyone who has offered their prayers and support....THANK YOU THANK YOU! We are neither of us adventurous or risk-takers by nature (which doesn't explain how it is we're heading off to Tanzania) and we are blessed to have spent these years at Peace and will continue to feel a part of the life there. *sniff, sniff* Here come the tears again, and it's just not good to cry on the keyboard...
