At the risk of appearing to be lazy, I'm just cutting and pasting a paragraph from an email I sent to dear friends who are in the throes of changing ministry, with all the resulting ambiguities.  Maybe this might somehow apply to your life.  Or maybe it will just give you a greater insight into the realities of being a missionary.

As for being led out from one ministry and into another, with lots of ambiguities and uncertainties (when we just want a clear blue print to follow), we've certainly been there.  I am reminded particularly of when we were given the "left boot of fellowship" (as contrasted with the "right hand of fellowship") from our former mission.  We knew that God had given us a deep love for Cameroon, in spite of all the difficulties of our then ten years out here.  We knew that we were not ready to give up on Cameroon.  But we didn't know what, or even if, God wanted us to do.  So we decided to take an exploratory trip out here, asking God two questions.  And expecting Him to answer in a way we could understand, because we firmly believe He speaks our language.  We asked Him if He wanted us to be in Cameroon, or was this just our desire?  We asked Him, if He wanted us here, to show us what He wanted us to do.  And He did.  The answers didn't come all at once, in a nice little outline, with step two following step one in a clear way.  But His leading was clear.  As we took what looked to us to be step one, He began unfolding step two to us.  And He will do the same for you.  Sometimes He fills our hearts and minds with longings and desires that are very real, but rather obscure and unclear.  We can rest confident in Him that when it is time to take step 2, He will make that clear.  Often it is only as we glance back over our shoulders that we see His plan that was so clearly there all the time.  Rest in Him.  He has a future and a hope for you.  He knows the cry of your hearts.  He knows your human weaknesses and limitations.  He knows all about you and He is wonderfully able to lead and guide you into this new adventure in His time, in His way, and for His Honor and Glory.
