My "Un-Call"

I heard the term "Un-Call" used this morning by a woman at my church who was giving her testimony at Bible Study. She talked about how she thought she had a "call" on her life, made all moves in that direction and then at a very important moment God spoke to her and gave her the "Un-Call," telling her that this was actually not what He wanted for her.
I didn't really get it, but I liked the idea.
Well, this evening, I got my very own "Un-Call!"
Mark and I feel that God has called our family to adopt. We feel pretty certain that it will be from South Africa, as He has us so intimately involved with Acres of Love and the AIDS pandemic and the orphaned children there. So, out of obedience I thought that I should just start making steps in the direction of international adoption and see what happened. I talked with lots of people and did a ton of research on Christian agencies and learned that adopting from South Africa is not fully approved for the US right now. (soon though, hopefully) So, I just figured that maybe God wants us to be open to other African countries too, also terribly effected by the AIDS crisis. We went to a meeting tonight with an international agency and learned about the options of adopting from Ethiopia. And there, I got my "Un-Call!" Although my heart is broken for the the children all over the world who are suffering and who need homes, like the one I could give, I feel strongly that God does not want us to adopt to just adopt. And Mark expressed on the way home that he was feeling the same "Un-Call!" We both feel that God has something else planned for us. What? We do not have a clue, but going through an agency like this to adopt from just somewhere isn't it. We are fairly certain that God's plan for our adoption will look very different.
I have to be honest, this is killing me. I can't stand knowing that God wants adoption from me, and then He expects me to just sit and wait. I am not good at waiting! I want to do something, get busy, get "doing." Why the waiting?
Surely, I will look back at this time someday and be thankful to the God who knew I needed this time for Him to work in us and on our family and get things all just right. He's good like that! I have to just trust the call that Mark and I have both separately heard from God and have faith that in His perfect timing, we will hear from him again and know what to do next.
